If you want to add Welsh language to source code, you should do these:

1. Add language code in GOOGLE_TRANSLATE_SELECT_LANGUAGES_CODES

2. Add language info in GOOGLE_TRANSLATE_SELECT_LANGUAGES

3. Add Welsh language class and style in https://github.com/i7eo/google-translate-select/blob/master/packages/theme-chalk/src/google-translate-select.scss#L82

That's all.
