• Added validation for Ghana Card numbers
  • Format: GHA-XXXXXXXXX-Y where X are digits and Y is a check digit

Thanks for this PR! Since VAT ID number validation is not a flagship feature of this library (and is not used by all users of this library), I'd like to keep it simple by handling it for economic areas only (eg. EU).

Unfortunately, accepting Ghana Tax ID validation opens a way for Tax ID validation for much more countries, which will ultimately result in code complexification.

I therefore believe Tax ID validation, if done on a country level, should be the scope of another separate library, which this one could in turn use. Eg. a node-tax-id-validator library.

Thank you for your response. I agree that this should be part of a separate package. I will go ahead and close this pull request.
