should we update this to be generic now?

Good call! I reworded this to update it and remove CoDICE things that I copied over.

This adds a helper function to combine segmented packets together after XTCE parsing. We can't handle this in the XTCE definition itself due to the variable length packets. We also need to update the Ultra packet definition to have a larger variable length field because the header items are actually only stored in the first packet, not all the middle/last packets too.

Change Summary
This adds a general helper to combine segmented packets together after the XTCE parsing. This required an updated to the XTCE xml so that the header fields aren't read in on the middle/last packets. This means we need to extract those fields manually after the XTCE parsing and combining of segmented packets. That is ultra specific, so I put the extraction function in the Ultra namespace.
