Explore extracting packets from transfer frames

[medley56]

Frames are a higher level of structure that exists in packet streams during downlink. Some cubesats and early testing data still contains these frames and the CCSDS packets must be pulled out of the frames before we can run them through the XTCE-based parser.

Explore adding a layer in space-packet-parser that is able to extract packets from transfer frames. The result should be a binary stream/file/object that is suitable for use with the XTCE-based parser.

One big anticipated challenge is that packets coming out of frames are prone to errors. I do not have the expertise to know how to generally solve this problem but we might be able to pull some knowledge from Ops or Ops SW experts.
