Rob Watson f9d6c66f7e Bug fix: Complete frames as soon as it is possible 
It should not be necessary to wait for the subsequent sync word to
determine that the current frame is complete - this can be assured
simply back checking the expected frame size against the actual bytes.

This ensures that completed frames are made available immediately, and
avoids dropping a single frame from every binary stream that is
processed.

MPEGAudioFrameParser

Given a series of binary packets, extract any complete MPEG audio frames that can be found and return them to clients.

In theory supports all of MPEG layer 1, 2 and 3 and versions 1, 2 and 2.5, but is most useful for (and has been most thoroughly tested with) layer 3 (MP3) files.

Usage

Currently WIP. See the moduledoc for usage examples.
