Julien Moutte 6f9006c9b9 riff: Manually calculate bitrate of ADPCM streams 
Some ADPCM encoding tools like Oxelon generate WAV files with
wrong format header declaring an invalid bitrate.

As wavparse uses the average bitrate to calculate timestamps
and duration the decoder can be confused by receiving timestamps
completely out of sync with the decoded samples.

ADPCM is a CBR audio codec so we can calculate the average bitrate
instead of trusting the format header.
