Correct CSV and sqlite support for location group

Add CSV header and sqlite schema support for the newly added location group, along with the necessary functions in the starlink_grpc module to expose the field names and types for that group. This really should have gone in with the prior change.

Also, correct the order of the ping_latency and ping_loaded_latency groups in the CSV header, which was backwards. This would have resulted in an incorrect CSV header if both those groups were selected.
