Enhance SRT parsing and optimize subtitle loading. Also some EventInfo fixes

[DimitarCC]

This pull request introduces significant improvements to subtitle parsing and event handling, focusing on performance, maintainability, and feature support. The most notable changes include a major refactor of the SubRipParser for faster and more robust SRT subtitle parsing, additional event handling in EventInfo.py, and improved subtitle loading logic.

Subtitle Parsing Improvements:

• Major refactor of SubRipParser in SubRip.py:
  • Rewrote SRT parsing to use a faster, single-pass line-based approach instead of regex-heavy parsing.
  • Improved tag and style handling with precompiled regexes and simplified logic for color and style parsing.
  • Added robust helper methods for tag removal, color extraction, and style detection, making the code more maintainable and efficient.

Event Handling Enhancements:

• EventInfo.py now listens for two new service events: evUpdateTags and evUpdateIDv3Cover, ensuring that the UI responds to more metadata changes.
• Fixed a bug in gotEvent where the internal service reference is now correctly cleared on all relevant events, improving state consistency.

Subtitle Loader Logic:

• Improved loadSubtitles in SubtitleRenderer.py to return a boolean indicating success, clarifying the method’s contract and simplifying error handling for SRT subtitles.
