Changes in v1.1.0 compared to version v1.0.4:
• complexity reductions for mp3PRO encoding by 30-50%
• ignoring the CRC check when playing mp3/mp3PRO files
• improved accuracy of the time slider for VBR and ID3v2 tagged files
• improved robustness when playing corrupted mp3/mp3PRO files
• added an option to encode the Original File Length in the bitstream, for such files the decoder would output a sample accurate .wav file on output
