add large ASCII fonts and font cycling to live modev0.3.0main

- Add 4 new ASCII art fonts (mono12, rebel, ansi, ansiShadow) adapted from pomo project
- Implement random font selection on startup when no font is specified
- Add 'f' hotkey in live mode to cycle through fonts
- Update LICENSE with MIT attribution for pomo fonts
- Update README with comprehensive font documentation
- Bump version to v0.3.0
