Fix disabling check digit validation of Mexican CURP

arthurdejong · arthurdejong · commit 02dec52602ae · 2022-01-09T17:13:20.000+01:00
The validation functions supported an optional parameter to disable check digit validation in the number that didn't actually affect validation and was most likely accidentally copied from the RFC module. Fixes 50874a9 Closes arthurdejong#285
