Issue #483: these circled-letter suffixes are in-list markers for
human readers (subscription-required, geo-blocked, YouTube-sourced,
etc.), but were leaking into the generated tvg-name verbatim (e.g.
tvg-name="Rai 1 Ⓖ"), breaking EPG matching for any provider keying
off channel name. Now stripped from tvg-name only; the display name
after the comma still shows the marker as before.
- Sanitize the channel number field for embedded double quotes; the
previous fix (#1124) covered group/name/logo/epg but missed
tvg-chno, leaving the same attribute-injection vector open via the
"#" column.
- Add missing "kenya" and "nigeria" entries to COUNTRY_CODES so those
channels get a tvg-country attribute in the generated playlist.
- Sync README.md and flag_order.txt with lists/: add missing flags for
chile, egypt, saudi_arabia, indonesia, kenya, nigeria in their
proper geographic groups.
- Add .gitignore for __pycache__/*.pyc.
