Need to replace internal CAM-SIMA input data streams with CDEPS

### What is the feature/what would you like to discuss?

In CAM much of the code for reading and interpolating file data is developed and managed internally. However, this adds a maintenance burden on the core development team, and can result in missing out on features and bug fixes provided by others.

To help alleviate this burden, and align CAM-SIMA with other CESM components, it would be good to replace these internal routines with [CDEPS](https://github.com/ESCOMP/CDEPS), which should be able to handle the file reading and time/space interpolation needed for CAM-SIMA.

### Is there anyone in particular you want to be part of this conversation?

_No response_

### Will this change (regression test) answers?

I Don't Know

### Will you be implementing this enhancement yourself?

Any Software Engineer can do this
