Prep for multi-fw and publishing on GitHub

### Added

- `.gitignore` for kpatch output
- Auto detect console type and firmware in `config.mjs`
  - Used elsewhere to determine which offsets/patches/ROP chain are used
- WIP: Add 8.50-9.60 support
  - All offsets found
  - Running into some issue here. Wiped out my JOP chains to redo them...

### Fixed

- Call `lapse.mjs` rather than `code.mjs`
- Makefile for kpatch builds all currently available

### Changed

- Use relative locations rather than absolute
- Changed kpatch binaries to just be shellcode vs full ELFs
  - 5,216 bytes to 257 bytes.
- Build kpatch binaries with `-Os` rather than `-O`
  - 257 bytes to 233 bytes.
- Renamed/Formatted `CHANGELOG.md`, `README.md`, and `LICENSE`
