Write ID3v2.3 genres with multiple references to ID3v1 genres (#988)

Browse Source 
As described in id3v2.3.0.txt (4.2.1, TCON), multiple genres are
only possible as references to ID3v1 genres with an optional
refinement as a text. When downgrading multiple genres from
ID3v2.4.0, they are now converted to numbers when possible and
the first genre text without ID3v1 reference is added as a
refinement. The keywords RX and CR are supported too.
