Wrong culture validation in Contact-constructor

[cyrillgisin]

Type of issue

[x ] Bug
[ ] Question (e.g. about handling/usage)
[ ] Request for new feature/improvement

Expected Behavior

When instantiating a new Contact, the library should not check the ISO 3166-1 (two letters) code with CultureInfo.GetCulture() because this list is incomplete.

Current Behavior

The library throws a SwissQrCodeContactException.

Possible Solution (optional)

Class: PayloadGenerator. Private constructor for Contact.
Please remove the following lines of code:
if (!((IEnumerable<CultureInfo>) CultureInfo.GetCultures(CultureTypes.SpecificCultures)).Where<CultureInfo>((Func<CultureInfo, bool>) (x => new RegionInfo(x.LCID).TwoLetterISORegionName.ToUpper() == country.ToUpper())).Any<CultureInfo>()) throw new PayloadGenerator.SwissQrCode.Contact.SwissQrCodeContactException("Country must be a valid \"two letter\" country code as defined by ISO 3166-1, but it isn't.");

Steps to Reproduce (for bugs)

Instantiate a Contact with the Two-letter-code "GH" for Ghana (parameter: "country"), which is an official ISO 3166-1 code but missing in CultureInfo.GetCultures() from .Net Framework

This is fixed in 7e6cc92 Since .NET still doesn't bring a complete list/all-in-one solution for the ISO codes, I decided to add an external solution. If you disagree with the code changes, feel free to re-open the issue. :-)
