- All tests passing

- Updated README and image
- Added itoa to stdlib
- Implemented modulus math for bcc which has none in the stdlib
- Updated the build scripts to work on Ubuntu 22
- Added bochsrc with some useful overrides (new bochs bios in ubuntu is broken, use the legacy)
- Made most of stdlib compile and run under GNU C for testing
- Improved the tokenizer so it will return tokens of more than one character
- Moved the basic parser from using void pointers to store values to using basic_value unions to represent possible types
- Added tests for the basic tokenizer
