chore(isTaxID): test against valid and invalid US TIN prefixes (#1408)

dspinellis · web-flow · commit db0a40227e0b · 2020-08-19T09:29:25.000+03:00
The existing isTaxId validation tests only checked the format,
while the validation code also tests for valid (US campus)
prefixes.  The added tests, check that the prefix validations
actually work.
