Summary:
- A bunch of optimizations guided by python profiling (esp. py-spy)
- Big one is optimizing Record/RecordSet attribute access
- Adds tracemalloc printout when running test_replay with PYTHONTRACEMALLOC=1 (on PY3)
(but memory size is barely affected by these changes)
- Testing with RECORD_SANDBOX_BUFFERS_DIR, loading and calculating a particular
very large doc (CRM), time taken improved from 73.9s to 54.8s (26% faster)
Test Plan: No behavior changes intended; relying on existing tests to verify that.

Summary: When a formula raises an exception, we store that in the cell in memory. In Python 3, exceptions have a `__traceback__` attribute, which includes all the stack frames and local variables. This has huge memory leak potential. We already strategically format the exception when needed, we don't need to keep storing the actual traceback object.
Test Plan:
Manually tested that tracebacks are still sensible.
To check the effect on memory usage, made a simple test doc with 30k rows all containing an exception, and here's what ps aux says:

Summary:
Added a new object type code `l` (for lookup) which can be used in user actions as a temporary cell value in ref[list] columns and is immediately converted to a row ID in the data engine. The value contains the original raw string (to be used as alt text), the column ID to lookup (typically the visible column) and one or more values to lookup.
For reflists, valueParser now tries parsing the string first as JSON, then as a CSV row, and applies the visible column parsed to each item.
Both ref and reflists columns no longer format the parsed value when there's no matching reference, the original unparsed string is used as alttext instead.
Test Plan: Added another table "Multi-References" to CopyPaste test. Made that table and the References table test with and without table data loaded in the browser.

Summary:
When a value $B.A is a ReferenceList, returning it in an Any column can cause
an "unmarshallable object" error, if the RecordSet happens to be storing
row_ids in the form of a nested RecordList object. This happened consistently
when $B.A started off as another type and got converted to ReferenceList.
A specific manifestation was when a reference column $B uses "A" as a display
column, and this column gets converted from Text to ReferenceList.
Test Plan: Added a test that reproduces the problem.

Summary:
Traceback is available on the Creator Panel in the formula editor. It is evaluated the same way as for normal formulas.
In case when the traceback is not available, only the error name is displayed with information that traceback is not available.
Cell with an error, when edited, shows the previous valid value that was used before the error happened (or None for new rows).
Value is stored inside the RaisedException object that is stored in a cell.
Test Plan: Created tests

Summary:
This makes it possible to set the type of a column to ReferenceList, but the UI is terrible
ReferenceList.ts is a mishmash of ChoiceList and Reference that sort of works but something about the CSS is clearly broken
ReferenceListEditor is just a text editor, you have to type in a JSON array of row IDs. Ignore the value that's present when you start editing. I can maybe try mashing together ReferenceEditor and ChoiceListEditor but it doesn't seem wise.
I think @georgegevoian should take over here. Reviewing the diff as it is to check for obvious issues is probably good but I don't think it's worth trying to land/merge anything.

Summary:
- Replace unicode strings with byte strings when decoding values in sandbox.
- Columns that rely on float values should derive from NumericColumn, so
that set() ensures that a float is stored even if loading an int.
- Parse unmarshallable values (['U']) into an object that can be encoded
back to the same value (rather than info a RaisedException).
- Compare NaN's as equal for deciding whether a change is a no-op.

- Removed a tiny bit of unhelpful logging
Test Plan:
Added a test case that reproduces several causes of Calculate
discrepancies by loading various values into various types of formula columns.

Summary:
- Introduce a new SQLiteDB migration, which adds DB columns for formula columns
- Newly added columns have the special ['P'] (pending) value in them
(in order to show the usual "Loading..." on the first load that triggers the migration)
- Calculated values are added to .stored/.undo fields of user actions.
- Various changes made in the sandbox to include .stored/.undo in the right order.
- OnDemand tables ignore stored formula columns, replacing them with special SQL as before
- In particular, converting to OnDemand table leaves stale values in those
columns, we should maybe clean those out.
Some tweaks on the side:
- Allow overriding chai assertion truncateThreshold with CHAI_TRUNCATE_THRESHOLD
- Rebuild python automatically in watch mode
Test Plan: Fixed various tests, updated some fixtures. Many python tests that check actions needed adjustments because actions moved from .stored to .undo. Some checks added to catch situations previously only caught in browser tests.
