dcp_inspect: Audio analysis from merged discrete channels

Depending on asset size asdcplib will either write RIFF WAV or
RF64. This patch simplifies the setup for analysis by writing
to single-channel fifos and making sox merge those to do its
work based on -t wavpcm. There were issues with sox's libsndfile
support for RF64 so we want to avoid using that.

Note that this is merely a workaround as sufficient RIFF length
provided asdcplib will still switch to writing RF64 single-channel
files and we would again run into the issue -- a related patch
rescues early from this, though.

asdcplib's deciding factor is RIFF_LENGTH. When bigger than
MAX_RIFF_LENGTH (0xFFFFFFFF) it will write RF64 (both single- and
multi-channel).
