Support custom type fields when doing "schema init".

[zackerydev]

Is your feature request related to a problem?

Not necessarily - however I do think it would help onboarding new databases to Neosync.

Describe the solution you'd like

When running Neosync against a schema with custom types, it would be really helpful if Neosync could dump the types and recreate them on the destination for me when "Init Schema" is true (or alternatively another toggle).

Describe alternatives you've considered

Right now I do a pg_dump --schema-only and run those commands manually on my Destination.

Additional context

It does get difficult when dealing with multiple schemas but even if it could just sync all custom types that would be awesome.

Thanks for building such a cool product!
