- 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.
