Improve performance of row ids

[jsdt]

Description of Changes

This makes a few performance improvements. It is pretty similar to #179. The key changes are:

• This updates how rowIds are created. For tables with a primary key, it is the primary key value. Otherwise it is a base64 encoding of the whole row. Previously the rowId was always a string representation of the entire row, even if we had a primary key.
• This gets rid of the very slow OperationsMap, replacing it with a standard Map. This is done by defining a way to turn any AlgebraicValue into a primitive that can be used as a Map key. This conversion is basically free for any primary keys, since they have primitive values.

This also has the fix of using concat instead of push(... that was in #179.

Since I was already making some changes in the TableCache, I added some more context to log messages, so hopefully any future bug reports will be easier to look into.

These changes also give us a way to make find efficient, but I didn't put it in this PR.

Requires SpacetimeDB PRs

Requires this codegen change clockworklabs/SpacetimeDB#2671, so we need to wait for the next release.

I'm going to leave this as a draft until we release a version with the required codegen changes.

Once we get this codegen change released, which adds the CLI version to the generated typescript code. I can add an assertion in the client that the generated code came from a compatible version.

Testing

There are some existing tests in db_connection.test.ts that cover parsing update messages, and this PR adds table_cache.test.ts, which has testing for applying row operations to the table cache (and the resulting callbacks).
