Added `--max-fps` flag to explicitly control max frame rate up to 120 FPS.
Introduced 1440p resolution support in `get_cols_from_res`.
Added Mode 6 to support 32M Colors with experimental HDR (display-p3).
Optimized CV2 capture and javascript buffer logic for live latency reduction.
Added yielding to Python async loop for high FPS encoding stability.
Updated README.md to represent these fork enhancements.
Added `--res` argument to both `stream_server.py` and `ascii_video_player2.py`
to easily set higher quality/density ASCII and pixel rendering.
The `res` argument maps `480p`, `720p`, and `1080p` presets
to appropriate column sizes (854, 1280, and 1920).
Updated `README.md` to document the new `--res` flag.
