DR3 Batch with Convert option

Add option to use convert instead of calibrate.

Updates pointers to Gaia archive, not pre-production server.

Gaiaxpy-batch Pre-DR3

Fixes, verbosity, gaiaxpy update. N.b. gaiaxpy still points to Geapre.

Gaiaxpy-batch Beta

Beta until data released (and testing can be concluded)

Beta Release

Unable to currently publish pre-DR3 or do final tests as servers are down
