🎨 Cleanup radiation transport

[je-cook]

Description

Does a bit of general housekeeping, no functional changes

Interface Changes

Removed MidPlaneProfiles is now a dataclass returned by the function 'midplane_profiles'. Changed the interface to CoreRadiation to take advantage of not needing to pass in the profiles individually.
