IsoCode639_1 is ambiguous

[bweben]

Hi

I'm trying to add a new language (or at least I'm trying to follow your contribution guide to add a new language).
Now I ran into a problem as the language Swiss German does not have a unique IsoCode639_1 code but probably shares the same as german. The IsoCode639_3 is GSW.

What is your preferred way to go forward? Add an imaginary IsoCode639_1 code? Or maybe add subfolders with the IsoCode639_3 code?

Thanks for your response and this awesome project.

Hi Nathanael, thank you for reaching out to me.

It's great that you want to contribute a Swiss German language model to Lingua. I think it's perfectly valid to use the existing IsoCode639_1.DE for Swiss German. You then just need to add IsoCode639_3.GSW as you have already found out. I haven't tried it yet but there should not be any problems if you assign the same iso code to more than one language. It is the correct way to do. If you encounter any problems with this approach, then please let me know.

Looking forward to your PR. Thanks a lot. Und viele Grüße in die Schweiz. :)

Hi Peter

OK, I created a PR now. I had to change some things, see #164

Besten Dank, viele Grüsse zurück nach Deutschland :D
