If we intend to continue using obs_ctio0m9 and the related CI package, we need to port it to Gen3. This means:
- Write astro_metadata_translator translator
- Write an Instrument class and Formatter
Please close as Won't Fix if no-one cares and people are okay with removing the obs package. I don't think we've formally deprecated it but I might be wrong. I'm assuming this ticket is not a blocker on DM-DAX-12.
