Wrapping testSourceTable.py with pybind11 was part of DM-6297 but didn't really fit there.
Complete afw port to pybind11
Wrap leftover tests in afw with pybind11
Wrap testTicketDM-433 with pybind11
Use visitor pattern to clean up afw::table pybind11 wrappers
Looks fine. Minor suggestions on PR.
Thank you for the helpful review.
I adopted most of your suggestions.
