findimageoverlaps fails for Chandrayaan-2 OHRC data due to "Unknown" Serial Number collision

[Labdhi-forwork]

ISIS version(s) affected: 10.0.0

Description
I am attempting to perform a bundle adjustment on a pair of Chandrayaan-2 OHRC (Orbiter High-Resolution Camera) images using ISIS 10.0.0 by following https://astrogeology.usgs.gov/docs/how-to-guides/image-processing/bundle-adjustment-in-isis/ this documention. While spiceinit and footprintinit (Polygon object) complete successfully, findimageoverlaps fails printing the following error:
user error filename [path/to/cube].cub can not be added to serial number list.
Invalid serial number [Unknown] from file [path/to/cube2].cub

I ran getsn on both the cubes and the output for both was "Unknown".

If you could please guide and help me resolve this issue, is it because there is no translation file (.trn) for chandrayaan2 which i checked in $ISISDATA/appdata or is it some other reason causing this error?

Yes, you are correct. Looks like we failed to add translation files to generate serial numbers for Chandrayaan2. I will put a PR in to fix this. In the meantime, you should be able to manually update the appdata files to get findimageoverlaps working, or you can wait until we release 10.0.0_RC2.
