HIT L1B - validate standard rates data

[vmartinez-cu]

This PR adds a test to validate the L1B standard rates data. As part of this work, the helper test functions file l1a_validation.py was updated to apply to L1B validation as well.

Closes #960

Updated Files

• l1a_validation.py
  • Renamed file to l1_validation.py
  • Updated file to support both L1A and L1B validation since some of the validation data reformatting work is common for both.
  • Added constants to the top of the file for readability
  • Added a helper function to reformat/prepare standard rates validation data for comparison with dataset
  • Split out consolidation of sector rate fields in the validation data into it's own function
  • Added type hints
  • Cleaned up documentation
• test_hit_l1b.py
  • added a test to validate standard rates product and use helper functions to carry this out
• test_hit_l1a.py
  • minor updates to reflect changes to the helper functions file

The checks are failing because the validation file is barely too large to add to the repo. Waiting for an updated file from HIT

@vmartinez-cu, this might be a great use-case for the remote file updates @bourque did in #1336

Yes, I was thinking that after Matthew shared his work during the tag up today. Though I think the problem is that all the numbers in the file have way more decimal places than defined for this product which results in a large file. When I reduce them to just one decimal place, the file size goes down by half. I'm following up with HIT on this
