ytcFilter per RomainLK, Kento Nishi

Capture messages from YouTube chat based on filter rules.

YtcFilter works alongside the standard YouTube chat and is compatible with third-party addons and websites such as Holodex. Many types of filters are supported, including:

- Author roles (Moderator, Member, Channel Owner, Verified, etc.)
- TL tags ([EN], [JP], etc.)
- Message types (superchats, membership messages, etc.)
- Text filters (contains, starts with, ends with, equals, regex, etc.)

Filtered chat messages are archived into persistent storage. Message logs can be easily imported/exported as text files, json files, or screenshots.
