stream/dvbin: add support for delivery system ISDB-T 

This is similar to DVB-T, but requires slightly different treatment
as there is no T/T2 differentiation.
Use a new channels.conf.isdbt file as channels config file.

``--dvbin-file=<filename>``
Instructs mpv to read the channels list from ``<filename>``. The default is
in the mpv configuration directory (usually ``~/.config/mpv``) with the
filename ``channels.conf.{sat,ter,cbl,atsc}`` (based on your card type) or
``channels.conf`` as a last resort.
filename ``channels.conf.{sat,ter,cbl,atsc,isdbt}`` (based on your card
type) or ``channels.conf`` as a last resort.
For DVB-S/2 cards, a VDR 1.7.x format channel list is recommended
as it allows tuning to DVB-S2 channels, enabling subtitles and
decoding the PMT (which largely improves the demuxing).
