Change Description

This introduces a new argument --output-unframed-data to the fprime-gds that allows capture and output of the unframed (junk) data that is discarded by the deframing process. This is needed for several reasons:

1. Sometimes data is multi-plexed, that is, frames come down mixed with something else (like console data)
2. Sometimes this data is necessary to understand bugs and other issues
3. Sometimes no data loss is acceptable even-if corrupted

This option allows users to output it when the flag is supplied. When not supplied, the data is discarded as it was previously.

Fixed some other issues:

1. Logs drop-down jumping about: Log Dropdown Jumps About fprime#2381
2. Logs pane clearing current data when erred preventing user from seeing what was there: Stop Clearing Log Pane Output on Shutdown fprime#2380
3. Better scrolling of log pane data. Fixes: GDS Log Scrolling fprime#2379
4. Python log output in GDS is no-longer in triplicate. Fixes: GDS Logs in Triplicate fprime#2378

Primarily fixes: nasa/fprime#2382

Rationale

See above.

Testing/Review Recommendations

Tested by putting out-of-frame data into Ref's downlink.

Future Work
