There's also partial support for viewing XRF spectra, but it is not done yet. I'll come back and work on that in a new PR.

Things to do before merging:

• add tests
• write docs
• update iconfig_testing.toml
• flake8, black, and isort

[canismarko]

Fixes:

• Add sample_name to the run_browser plotting label in addition to the uid #326
• Allow the run browser to select a data stream for plotting #305
• Additional filters to add to the run browser #279
• Fix tests for the run_browser #189
• Disable the relevant widgets while loading data in the run browser #161
• Implement checkboxes for filtering by current proposal and/or ESAF in the run browser #99

Reviewed this with the team at the beamline, so skipping an explicit review of this PR.
