Modify some outdated docs to properly reflect on class functionality. Also, modify the names of three classes to better reflect their use. Original names are alised for compatibility.
Generally just to remove extremely large or small weights which may cause numerical issues.

Gains are set to 1 when calibration determines some frequencies are bad. The gain interpolation region will also produce junk data, so this is designed to mask that.
This PR has 3 commits:
This task is run for each individual timestream file then masks are combined and applied. It also requires subsequently using
ExpandMask
fromch_pipeline
to actually mask the gain interpolation region AFTER individual timestreams have been grouped into a full day.
