Profiling results for overall audio decode and the rematrix_channels function
in particular are as follows:

8:8 function 223.4 12.8 93.8 5.0 100.0% +138.3%
The assembly version has also been tested with a fuzz tester to ensure that
any combinations of inputs not exercised by my available test streams still
generate mathematically identical results to the C version.
