Closes #3494.

I'm making some assumptions about the imap_140.tf that will be available upstream soon. Once we have that file, I can replace the file imap_processing/tests/spice/test_data/imap_140.tf in this PR with the official version and make any necessary tweaks to this PR.

EDIT: I had totally forgotten that @tmplummer had provided me with the correct imap_140.tf file. Updated this PR by using the official version of that file.

I think you raised a good point about the unused functions:

haven't taken out the now-unused (except for tests) get_lo_pivot_boresight and lo_instrument_pointing functions. I didn't see a pattern of warnings.warn or raise DeprecationWarning anywhere else so I've left them in. Let me know if these should be taken out in this PR or we can leave that for the future.

I'd say that you should go ahead and remove them.

PR #3518 is using these functions, so once that is merged, I'll remove these and update their references accordingly.
