Add SWXSOC Science Filename Parsing Test for Instrument Package Compliance

[dbarrous]

This PR refactors the padre_sharp instrument package to add back the create_science_filename functions and old util test suite so they can be managed by the instrument package team.

It also adds the test_validate_swxsoc_science_filename test to ensure that instrument teams can define their own create_science_filename implementations while maintaining compliance with the SWXSOC naming convention.

The test will be added to all other instrument packages after this PR, test for reference:

def test_validate_swxsoc_science_filename(
    expected_mission, expected_instrument, expected_time, expected_formatted_time,
    expected_level, expected_descriptor, expected_version, expected_file_extension, expected_filename
):
    """
    Validate that filenames generated by `create_science_filename` conform to the SWXSOC naming convention.

    This test ensures:
    - Instrument teams can define their own `create_science_filename` implementations.
    - Filenames adhere to SWXSOC's required format.
    - Handling of blank descriptors is correct.
    - Test files are properly labeled with "test" in their filename.
