iptv_auto: Add support for m3u "channel-number" tag

SiliconDust recently added m3u playlist generation support to the
HDHomeRun products.  They use "channel-number" for the channel
number, so add support for that value to TVHeadend.  It is used as
a fallback only if the previously-supported "tvh-chnum" and
"tvg-chno" tags aren't present.  This should be particularly useful
for usage with ATSC 3.0 channels, as those aren't supported in the
libhdhomerun library that TVHeadend normally uses for HDHomeRun
devices.  Without this, the channel number for all channels
imported from the HDHomeRun m3u is "0".
