Update the Python TUVX class to allow updates to grid and profile data.

Acceptance Criteria

• Grid and profile values can be updated after creation of a TUVX instance and are used in TUV-x calculations

Ideas

• Consider having grids/profiles be properties of the TUVX class, so they can be set using regular array syntax instead of by calling update functions like in the C/C++/Fortran APIs
• Create an in-code equivalent of the src/test/data/tuvx/fixed/config.json configuration with grids and profiles that have the correct dimensions but 0s for all values. Update the values of grids and profiles after creation of the TUVX instance and compare the output vs a from-file TUVX instance in a test.
