Please add ogg-vorbis tags

[marsdbr]

Hello schreibfaul1 ,

thank you very much for the library, it makes my project perfect.
I would like to ask you, if it is possible to implement ogg-vorbis tag reading.
Unfortunately ogg-vorbis has no icy-title tag, but i would like to show the title equivalent to the mp3 icy-title on my radio display.

Regards
Mars
