up.
- Problems was caused by call to `setGroupByColumns` which modifies
the sections viewFields. Diff fixes it by adjustin slightly the
ordering of function call in `_setXAxis()`.

Summary:
Adds a `data-grist-col-ref` attribute to the copied HTML, then uses that when pasting to look up the source column and retrieve info about it. Copies the info into the target column if:
- The document is the same (the docId hash matches)
- The source column still exists and has the same type as when copied
- The source type isn't Text, because in that case it's nice if type guessing still happens
- The target column is empty, meaning it has type Any (we check earlier that it's not a formula column)
The info copied is the type, widgetOptions, and reference column settings (visible and display columns) but not conditional formatting.
The changes are mostly in a function `parsePasteForView` which is based on `BaseView._parsePasteForView` but ported to TypeScript in a new file `BaseView2.ts`.
Added a useraction `MaybeCopyDisplayFormula` exposing an existing Python function `maybe_copy_display_formula` because the target column needs a slightly different display formula.

Summary:
- Removed string parsing and some type guessing code from parse_data.py. That logic is now implicitly done by ValueGuesser by leaving the initial column type as Any. parse_data.py mostly comes into play when importing files (e.g. Excel) containing values that already have types, i.e. numbers and dates.
- 0s and 1s are treated as numbers instead of booleans to keep imports lossless.
- Removed dateguess.py and test_dateguess.py.
- Changed what `guessDateFormat` does when multiple date formats work equally well for the given data, in order to be consistent with the old dateguess.py.
- Columns containing numbers are now always imported as Numeric, never Int.
- Removed `NullIfEmptyParser` because it was interfering with the new system. Its purpose was to avoid pointlessly changing a column from Any to Text when no actual data was inserted. A different solution to that problem was already added to `_ensure_column_accepts_data` in the data engine in a recent related diff.
Test Plan:
- Added 2 `nbrowser/Importer2` tests.
- Updated various existing tests.
- Extended testing of `guessDateFormat`. Added `guessDateFormats` to show how ambiguous dates are handled internally.

- Adds guessDateFormat using moment-guess to determine the best candidate date format. The logic may be refined for e.g. lossless imports where the stakes are higher, but for now we're just trying to make type conversions smoother.
- Uses guessDateFormat to guess widget options when changing column type to date or datetime.
- Uses the date format of the original column when possible instead of guessing.
- Fixes a bug where choices were guessed based on the display column instead of the visible column, which made the guessed choices influenced by which values were referenced as well as completely broken when converting from reflist.
- @dsagal @georgegevoian This builds on https://phab.getgrist.com/D3265, currently unmerged. That diff was created first to alert to the change. Without it there would still be similar test failures/changes here as the date format would often be concretely guessed and saved as YYYY-MM-DD instead of being left as the default `undefined` which is shows as YYYY-MM-DD in the dropdown.

Summary:
When two widgets are linked by same-record linking, and the source of that link is also filter-linked, then it will pick up default values from its own filter-link source, but the same-record-link target didn't. This fixes that so that default values are filled in intuitively.
Moved the logic of linkingState, linkingFilter, and getDefaultColValues from BaseView.js to LinkingState.ts and ViewSectionRec.ts. In particular getDefaultColValues is now a property of LinkingState which may be copied from the source view section for a same-record link.
Note that `ViewSectionRec.linkingFilter` no longer uses `computerBuilder` and thus doesn't ignore dependencies inside LinkingState any more. I couldn't figure out how to make `linkingFilter` a `pureComputed` (otherwise I get recursion errors) that ignores dependencies. In any case, it's now important to have a dependency on `srcSection.linkingState()` for `getDefaultColValues` to work correctly, so I think this is for the best.

While working on type conversion, I ran into a bug when multiple action groups belonging to a bundle are quickly sent. `DocData._sendActionsImpl` can set the same `linkId: this._lastActionNum` on multiple action groups before `_lastActionNum` is updated with a result from the server. Only one of these groups gets saved in `UndoStack._linkMap` so undoing a bundle misses out on some action groups.
This diff associates each `linkId` key with an array of action groups instead of just one, then combines them all together when undoing.
Test Plan: I've confirmed that this fixes my problem within my type conversion diff, but I haven't found a way to reproduce the general problem in master. I think the existing tests are probably fine since undo is tested extensively everywhere, but I'd also like to see if there are existing bugs which this fixes.

1) it prevents user from adding non numeric column as series and
2) it makes sure that if there is a non numeric series it does not mess up the chart (it still can happen that a non numeric series ends up in charts even with 1) for instance if users convert a series' column to a non numeric column for instance).

Summary:
Previously, ref/reflist columns were formatted entirely based on their visible column, since they received values from the visible or display columns rather than the actual row IDs. This creates `ReferenceFormatter` and `ReferenceListFormatter` which still delegate most of the formatting work to a visible column formatter but fix a few issues:
- ReferenceList columns now actually use the options (e.g. date format) of the visible column to format their elements. Previously they were formatted generically because the visible column formatter wasn't expecting a list.
- Invalid references aren't formatted with an `#Invalid Ref` prefix.
- When the ref column displays the Row ID, it doesn't have a visible or display column. Previously this led to the references being formatted as just numbers in most cases, with special code in the widget to display them like `Table1[2]`. Now they are consistently formatted in that style throughout.
Test Plan: Updated existing tests.
