Performance issues

[antl3x]

Hey @djcunningham0. First, congrats for the amazing repo / project!

I'm opening this issue to discuss some improvements in the process_data algorithm.

I run a dataset of ~ 70k rows (matches) and it takes >140 minutes to finish.

Maybe we can do some changes to speed up things? Maybe use Numba?
