42 channels across 14 lists have an EPG column in their markdown table row
but the column is blank. The condition in Channel.to_m3u_line() only checked
for None (no EPG column at all) but not for an empty string, so these
channels got a tvg-id="" attribute in the generated playlist. An empty
tvg-id tells IPTV players "this channel has an EPG ID and it is the empty
string", which prevents EPG matching rather than falling back to name-based
matching the way a missing attribute would.
Changing `if self.epg is not None` to `if self.epg` makes both None and
empty string omit the attribute, matching the existing pattern used by
the chno and country_code attributes on the lines just above.
Add ISO 3166-1 alpha-2 country codes via tvg-country attribute
to all #EXTINF lines, enabling IPTV players to filter and display
channels by country.
