Use a library like `rich` to create prettier progress reports

We have a few places we do long-running jobs:

• FHIR bulk exports
• I2b2 bulk exports
• I2b2 streaming reads from local files
• Copying ndjson files from destination to local
• To a lesser extent, each ETL task
• MS deid tool runs (can take a while, but we don't get any status updates)

It would be nice if we had more unified output for that. The rich library (used by pip) is a strong contender, but maybe some implementer research will yield something else.

There are two "consumers" of nice output:

• Console users
• Logging

Which I only mention because it's worth testing that whatever solution used doesn't generate a million lines of a bouncing hashmark when it doesn't have a real console that can "backspace".

The bulk export code might be a good first step for this feature. It has some interesting existing complexities that we'd want to know how to carry over in rich (or whether they no longer make sense):

• Custom messages from server
• Partial completion events (some of the files finishing downloading)
• Total time elapsed
• Time about to wait (maybe not necessary if rich makes waiting not feel so bad)

This got done a while back - we have generally nice feedback via rich these days. Room for improvement, but I'll close this general issue.
