Please add more icons (and options) for Bulgarian keyboards

[LuboGD]

Hello, I would be grateful if you would add more icons (and options) for Bulgarian keyboards. I see that you already have 2 for Czech, so the code for Bulgarian should be easy to change to work in a similar way.

There are 2 frequently used Bulgarian keyboard layouts. At the OS level (where gxkb gets it's data of which layouts to display), they are called: Bulgarian (traditional phonetic) Bulgarian (enhanced) (Actually, there is a variant similar to traditional phonetic called new phonetic too, so 3 total) But the distinction between enhanced and (either) phonetic is much more important, because they are totally different layouts new and traditional phonetic have some differences, but also more similarities, so telling them apart is not as critical, though also useful in some contexts I have (using your existing Bulgarian flag as a template), made the 3 icons such an addition requires, attached here. named in the same style as the 2 Cz icons: bg_phonetic.png (identical visually to your bg.png simply renamed to correspond to traditional phonetic) bg_bds.png (for the enhanced, also called BDS layout) bg_new.png (for new phonetic)

Thank you
