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.

Summary:
Adds `common/ValueGuesser.ts` with logic for guessing column type and widget options (only for dates/datetimes) from an array of strings, and converting the strings to the guessed type in a lossless manner, so that converting back to Text gives the original values.
Changes `_ensure_column_accepts_data` in Python to call an exported JS method using the new logic where possible.
Test Plan: Added `test/common/ValueGuesser.ts` to unit test the core guessing logic and a DocApi end-to-end test for what happens to new columns.

Summary:
- Adds a dependency moment-guess (https://github.com/apoorv-mishra/moment-guess) to guess date formats from strings. However the npm package is missing source maps which leads to an ugly warning, so currently using a fork until https://github.com/apoorv-mishra/moment-guess/pull/22 is resolved.
- 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.
Test Plan: Added a unit test to `parseDate.ts`. Updated several browser tests which show the guessing in action during type conversion quite nicely.

Summary: By default, new date columns show "YYYY-MM-DD" as the date format in the UI, but under the hood it's stored as null/undefined, which affects parsing during pasting and type conversion. This changes the underlying parsing to always default to YYYY-MM-DD, as if that format was explicitly selected, making things more consistent.
Test Plan: Updated some tests.

Summary:
- Rather than translate from moment format to that of bootstrap-datepicker, use
the customization methods to format datepicker dates using moment directly.
- Fix issue with parseDate() when format includes tokens like Mo or Do
- Fix issue in parseDateTime() that could produce an off-by-one error in date
depending on local timezone.
- When opening DateEditor, show AltText value if present.
- Add crossorigin=anonymous to scripts that were missing it (including
bootstrap-datepicker), to ensure that errors from them are reported properly
rather than as 'Script error.'
Test Plan:
Added test cases to parseDate() test for low-level fixes; added a
browser test for the fixed DateEditor behavior.

Summary:
- With a format like "DD-MM-YYYY" or "DD MMM YYYY", allow parsing dates
with two digit year or numeric month (like "16-8-21").
- Interpret two-digit years in the same way for moment parsing and for
bootstrap-datepicker.
- For partial inputs (like "8/16"), when a format is present, assume that
provided parts cover the date, then month, then year (even for a format that
starts with year).
