dcp_inspect: Make audio level bars more useful

The audio level bars in reel inspection allow
to quickly judge overall levels and presence of
audio in a given reel. E.g.

RMS -21.11 dBFS |▄|▄|.|▄|▄|▄|, Peak -1.56 dBFS |▅|▆|.|▅|█|▆|

shows peak RMS and Peak, respectively, for all
channels.

This patch changes the appearance of these bars
by separating channels with '|' and adding the
'.' marker for -inf dBFS.
