v1.2

1. Added better regex for countries with postal codes that could allow for or - between primary and extended codes. IE: In the USA a primary code of "12345" could also have sub codes separated by a dash or space, "12345-1234 OR 12345 1234". The previous regex's only accounted for 123451234, now the new ones allow (and expect) a dash or space between them.
2. In v1.1, 62 Countries did not have Postal Code Systems. 15 of those now have specific postal code formats - those 15 were updated.
3. For countries that do not have a Postal Code System, the previous description was "No Data", that has been updated to now say "NoPostalSystem" to be more descriptive than the previous ambiguous "No Data"

v1.1: Update CountryData_minify.json
