Added the gaia_release and gaia_epoch attributes #34

This PR generalizes the use of MAIN_GAIA_TABLE, by creating the gaia_release and gaia_epoch attributes. When MAIN_GAIA_TABLE will be set to DR4 in the future, then the epoch for transform_cat gets adjusted, based on the retrieved Gaia ref_epoch for the target.

I also adjusted a few instances of backtrack to backtracks (thanks for changing that @wbalmer!).

Fixes issue described in https://github.com/wbalmer/backtracks/issues/16#issue-2044970311

  • When Gaia DR4+ uses a different Epoch this hard-coded value needs to be updated.
