This repository's size is huge

[mcara]

This repository includes directories for MAST downloads as well as reference CRDS files bringing the size of this repository close to 4GB. In my opinion this is not necessary and all these directories should be removed from this repository.

In my recent clone of this directory (2022-02-15), it seems to be only about 1 GB (984 MB), and the vast majority (945 MB)of that is in the .git subdirectory.
I'm guessing that there have been images, FITS files, etc. under version control and since removed, but they live on in the .git history.

1 GB is also a lot of disk space for something that isn't cat videos.

Reducing the repo size would require rewriting the git history.

Only 500-ish commits to squash...

Going forward, maintainers need to be strict in the review process to not allow big data files (or any) being checked in.

One major issue is not clearing Notebook's cells before committing. (I think I was guilty of this early on in a different repo)

[pllim]

Proposal:

1, Push the current state of repo to another repo that no one will ever use (for history record keeping purpose).
2. Clear all the notebooks and unwanted data here.
3. Squash all the commits and force push to master.
4. ???
5. Profit!
