Is your feature request related to a problem? Please describe.
Possibly long term, Currently there is a command to add a MID to the filter table and subscribe to it. However short of a manual filter table file update, there is no way to remove unused MIDs from the filter table or unsubscribe from it.

If the the MIDs required are changing overtime in flight this could potentially lead to running out of space in the filter table even though MIDs are no longer being used. This in turn would force manual intervention to correct it.

Describe the solution you'd like
Implement a command to unsubscribe from a MID and remove the MID from the filter table.

(If needed it could be limited to MIDs with all its filters set to DS_UNUSED.)

Describe alternatives you've considered
Pushing an update to the table may not be feasible when needed in flight. Since it unsubscribes to the entire table, it also creates a small gap in telemetry recording on those MIDs that are not modified.
