Formatting of angle should probably support different cultures?

[Nickztar]

For some reason my AngleTest is now failing, is definetly unrelated to this my recent PR but might be worth opening a issue for. It's definetly a culture issue aswell. Probably just in how the formatting works.

This is the result from AngleTest -> IFormattableTest. Same for all cases.
String lengths are both 13. Strings differ at index 4. Expected: "413°.63911575" But was: "413°,63911575" ---------------^

Not sure if this is something important so figured I would open a discussion instead of a issue.

All of my tests pass so you are probably correct about culture settings.

Definitely was. Works correctly when adding this to the ShortFormat
return this.InternalValue.ToString("0°.0000####", System.Globalization.CultureInfo.InvariantCulture);

I updated this in 3.3.0.
