Stuck with Chandrayaan-2 TMC-2 Fore/Aft processing (spiceinit / isd_generate errors)

**ISIS version(s) affected**: 10.0.0

**Description**

For my setup, I'm currently running ASP 3.7.0, ISIS 10.0.0_RC2, ALE 1.2.0, and USGSCSM 2.0.2.

I've already ingested the Fore and Aft data into .cub files along with their .img and .xml files. When I try running spiceinit on them, ISIS points me toward the CSM camera model with this message:

"Cube [PATH] has instrument [CH2_TMC_FORE]. Support for AFT or FORE cubes is not available in the chandrayaan2 TMC-2 ISIS Camera model. Please use the CSM camera model by running csminit ."

Since I'm on recent builds across the board, I'm wondering if I'm missing a required intermediate step or handling the input files incorrectly. Any tips or a working workflow would be a huge help!

Start with the ingested Fore and Aft .cub inputs and reproduce the spiceinit error using the stated ISIS, ASP, ALE, and USGSCSM versions. Read the spiceinit and csminit entry points and trace how the CH2_TMC_FORE and AFT inputs are routed; done means a documented workflow processes both cubes without the reported errors.
