Can't write double BPM values to mp4 tag

[IJabz]

From https://java.net/jira/browse/JAUDIOTAGGER-476

M4aWriteTagTest fails if you try to use double bpm values, so use "300.5" instead of "300".

Would it be ok to change the following line in class Mp4FieldKey

from: BPM("tmpo",Mp4TagFieldSubType.BYTE, INTEGER, 2), to: BPM("tmpo", Mp4TagFieldSubType.TEXT, TEXT), //changed by UM

No I dont think so because TMPO is not defined by me so I think that if I let JAUDIOTAGGER write floating point numbers to this field it would break other applications, but if Im wrong let me know. But we added the FBPM field for floating point BPM so you can use that instead
