feat(weave_query): add ability to view traces on query panels

[domphan-wandb]

Description

🚧 This is WIP 🚧

Internal doc

This draft (as of PR creation) contains two ops and an api client to handle loading weave traces onto query panels.

• The query panel can be tested by using the expression project.traces({})
  • Another example with currently implemented payload fields: project.traces({filter: {trace_roots_only: true}, limit: 10000, offset: 0, sort_by: [{field: "started_at", direction: "desc"}]})

@nicholaspun-wandb , there are minor tweaks to be made like adding feedback and cost support, but I think some interesting meaty items to take on could be:

1. A spike on figuring out a more efficient way to get the column types of the calls
2. Adding feature flagging support to limit access to this op

Development Notes / Tips

I spent too much time toiling over the ops not matching only to realize that my changes to weave-public weren't being reflected in the dev environment.

Make sure you:

1. navigate to weave-python and pip install -e ./weave-public/weave_query/
2. every time you make a change to weave_query (python), [s]top and [r]eload weave_server.wandb thru governor. I found that I needed to do this to propagate code changes and flush any stdout I debug printed.
3. if you switch branches on core then switch back, make sure you redo step 1 from above.
4. Don't always wait for app.wandb's HMR. I found that this takes way too long due to import cycles (depending on the file you updated). Sometimes it's faster to [s]top and [r]eload it on governor.
