add a pyodide-based "sandbox" flavor (#437)
This adds a new `GRIST_SANDBOX_FLAVOR=pyodide` option where the
version of Python used for the data engine is wasm, and so can
be run by node like the rest of the back end. It still runs as
a separate process.

There are a few small version changes made to packages to avoid
various awkwardnesses present in the current versions. All existing
tests pass.

This is very experimental. To use, you'll need something with
a bash shell and make. First do:
```
cd sandbox/pyodide
make setup           # README.md and Makefile have details
cd ..
```

Then running Grist as:
```
GRIST_SANDBOX_FLAVOR=pyodide yarn start
```
should work. Adding a formula with content:
```
import sys; return sys.version
```
should return a different Python version than other sandboxes.

The motivation for this work is to have a form of sandboxing
that will work on Windows for Grist Electron (for Linux we have
gvisor/runsc, for Mac we have sandbox-exec, but I haven't found
anything comparable for Windows).

It also brings a back-end-free version of Grist a bit closer, for
use-cases where that would make sense - such as serving a report
(in the form of a Grist document) on a static site.

16a43edc2e (core) Upgrade friendly-traceback and its dependencies
Summary:
Upgrading the friendly-traceback package to include a fix that I specifically requested in https://github.com/friendly-traceback/friendly-traceback/issues/144 as a solution for the problem mentioned in https://grist.quip.com/HoSmAlvFax0j#MbTADAEcJb7 . Specifically, this shows a friendly explanation when using `len()` with a generator expression.

Also upgraded the dependencies `executing` and `stack_data` (which are mine) while I'm at it, although I don't expect this to really change anything.

Test Plan:
Existing tests. There was one test failure because of a new explanation about generic `Exception`s which I've suppressed.

Tested manually that the new explanation appears:

42afb17e36 (core) Run and test imports only in Python 3, upgrade openpyxl, fix weird date handling
Summary:
Python 2 only needs to be supported for the sake of old documents and formulas. This doesn't apply to the separate sandboxes that parse files for imports. Using Python 3 only allows using newer libraries and library versions. In particular, the latest version of openpyxl doesn't support Python 2. This will also make it easier to make other similar changes in the future, such as replacing messytables with a modern library. See https://grist.slack.com/archives/C0234CPPXPA/p1661261829343999?thread_ts=1661260442.837959&cid=C0234CPPXPA

The latest openpyxl is better at handling a particular edge case with broken dates in Excel, but still doesn't quite do what we want, so we monkeypatch it. Discussion: https://grist.slack.com/archives/C02EGJ1FUCV/p1661440851911869?thread_ts=1661154219.515549&cid=C02EGJ1FUCV

Setting `preferredPythonVersion` to '3' in SafePythonComponent ensures that JS always creates import sandboxes that use Python 3. Within Python, a module used by all imports will raise an error in Python 2. Python unit tests of imports are now only run in Python 3, using the `load_tests` protocol of `unittest`.

Test Plan: Mostly existing tests. Added another strange date to the Excel fixture.

6c90de4d62 (core) Switch excel import parsing from messytables+xlrd to openpyxl, and ignore empty rows
Summary:
Use openpyxl instead of messytables (which used xlrd internally) in import_xls.py.

Skip empty rows since excel files can easily contain huge numbers of them.

Drop support for xls files (which openpyxl doesn't support) in favour of the newer xlsx format.

Fix some details relating to python virtualenvs and dependencies, as Jenkins was failing to find new Python dependencies.

Test Plan: Mostly relying on existing tests. Updated various tests which referred to xls files instead of xlsx. Added a Python test for skipping empty rows.

bb8cb2593d (core) support python3 in grist-core, and running engine via docker and/or gvisor
Summary:
 * Moves essential plugins to grist-core, so that basic imports (e.g. csv) work.
 * Adds support for a `GRIST_SANDBOX_FLAVOR` flag that can systematically override how the data engine is run.
   - `GRIST_SANDBOX_FLAVOR=pynbox` is "classic" nacl-based sandbox.
   - `GRIST_SANDBOX_FLAVOR=docker` runs engines in individual docker containers. It requires an image specified in `sandbox/docker` (alternative images can be named with `GRIST_SANDBOX` flag - need to contain python and engine requirements). It is a simple reference implementation for sandboxing.
   - `GRIST_SANDBOX_FLAVOR=unsandboxed` runs whatever local version of python is specified by a `GRIST_SANDBOX` flag directly, with no sandboxing. Engine requirements must be installed, so an absolute path to a python executable in a virtualenv is easiest to manage.
   - `GRIST_SANDBOX_FLAVOR=gvisor` runs the data engine via gvisor's runsc. Experimental, with implementation not included in grist-core. Since gvisor runs on Linux only, this flavor supports wrapping the sandboxes in a single shared docker container.
 * Tweaks some recent express query parameter code to work in grist-core, which has a slightly different version of express (smoke test doesn't catch this since in Jenkins core is built within a workspace that has node_modules, and wires get crossed - in a dev environment the problem on master can be seen by doing `buildtools/build_core.sh /tmp/any_path_outside_grist`).

The new sandbox options do not have tests yet, nor does this they change the behavior of grist servers today. They are there to clean up and consolidate a collection of patches I've been using that were getting cumbersome, and make it easier to run experiments.

I haven't looked closely at imports beyond core.

Test Plan: tested manually against regular grist and grist-core, including imports
