Add alternate letterform for Latin Capital Letter Eng (Ŋ, U+014A) for some African languages

[agusbou2018]

The current form of Latin Capital Letter Eng (Ŋ, U+014A) at the Inter form family, looking like a capital N with a hook, is preferred only at Sami languages. I suggest to add an alternate letterform for Latin Capital Letter Eng (Ŋ, U+014A) that looks like an enlarged lowercase n with a hook, that is the preferred form for several African languages by using a Stylistic Set, Character Variant or localized forms for relative African languages (such as Ewe, Wolof or Luganda). Don't forget to keep the current N-form of the letter as the default form, as it's used in Sami languages.
