Pull request overview

Adds a new release CLI subcommand (and corresponding release() I/O function) to the IMAP data access tool, enabling users to submit release / early-release / unrelease requests for a given instrument and date range against the SDC API. A small utils module is introduced to host the ReleaseType enum used for validation.

Changes:

• New ReleaseType enum in imap_data_access/utils.py (release, early-release, unrelease).
• New release() function in imap_data_access/io.py that builds parameters and issues a request to the /release endpoint.
• New release subcommand in imap_data_access/cli.py with --instrument, --start-date, --end-date, --release-type, optional --release-number, validated by a _release_parser handler.

Just a couple of things to consider.

I know that we are in a crunch, so I won't hold this up, but I think the parameters for the release CLI are still a bit confusing and inconsistent.

Oh, interesting. I am glad I commented. This is not what I expected. Due to the different handling of this list of files from one release type to the next, would it be worth breaking it into different arguments. For release, the list of files to release is: "all files in the specified date range minus the files listed. But, for early-release and unrelease, the list of files here is the list to act on. Maybe this is too nit-picky, but I think it is good to have consistency in the UI to avoid confusion.

To add to this, it seems like for early-release and unrelease the date arguments are not required?

[tech3371]

I am planning to not support early-release and unrelease options yet on the lambda due to time crunch. Should I remove them for now?

Looks good!
