This module returns a hash containing basic information about a Musepack
file, as well as tag information contained in the Musepack file's APE tags.
See Audio::APETags for more information about the tags.

The information returned by Audio::Musepack->info is keyed by:

streamVersion
channels
totalFrames
profile
sampleFreq
lastValidSamples
encoder

Information stored in the main hash that relates to the file itself or is
calculated from some of the information fields is keyed by:

trackLengthMinutes : minutes field of track length
trackLengthSeconds : seconds field of track length
trackLengthFrames : frames field of track length (base 75)
trackTotalLengthSeconds : total length of track in fractional seconds
bitRate : average bits per second of file
fileSize : file size, in bytes
filename : filename with path
