Looks good, Wing! I have a few comments about variable names, but the code looks good.

I'm not sure about this, but I think you need an offset to account for the reference time system being defined from Jan 1, 2025 00:00:00. So I would expect another conversion from the packet time in seconds+nano seconds to the RTS time system.

Hi Carolyn,
Thank you for catching that. You're right. It shouldn't be loaded as RTS directly. I was doing it that way because I wrote my L0 saver to save in RTS, so originally I read it back into RTS as well. But I looked at the docs, and I think in the real case the packets will come down in GPS time. So in the new commit, I rewrote the saver and loader to read and write the L0 packet time in GPS. I think that's the right approach, but I'd still like to confirm with you.
Thanks!

Adds L0 loader, and its GUI module.
MModuleLoaderMeasurementsL0- parses the L0 file header, CCSDS primary/secondary headers, HIT_DATA. Auto-detects raw CCSDS vs. L0 with header.
