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:
Run JS with a value for SANDBOX_BUFFERS_DIR, then run test_replay in python with the same value to replay just the python code.
See test_replay.py for more info.
Test Plan:
Record some data, e.g. `SANDBOX_BUFFERS_DIR=manual npm start` or `SANDBOX_BUFFERS_DIR=server ./test/testrun.sh server`.
Then run `SANDBOX_BUFFERS_DIR=server python -m unittest test_replay` from within `core/sandbox/grist` to replay the input from the JS.
Sample of the output will look like this:
