[FEATURE] tidy exports from csv instead of API

[shannonpileggi]

Feature Request Description

You have such amazing functionality to tidy redcap data! It would be nice if there were user facing functions that could do the same for csvs exported from redcap as well.

Describe alternatives you've considered

Pain and suffering.

Additional Context

We were recently contracted for short term support for a database hosted in REDCap at an instution at which we did not have API access, and we received the data via csvs. Granting us API access was not feasible. Thank you for considering!
