Support for Musepack/MPC files

[McOrvas]

Hello Matthias,

first of all thanks a lot for your great work! I have used loudgain to process my music library, but I have some old Musepack/MPC files which cannot be tagged with your tool. To be honest I am not sure if Musepack respectively the used tag format supports the needed replaygain tags, but if it is technically supported: Would it be possible without without much effort to add support for Musepack files?

Best regards,
Manfred
