Erin 06b1184772 HoleyBytes, almost adhering the spec
- Changed instruction encoding to be faster to match on
- Implemented all instructions defined in spec
- Bytecode validation
- Assembler
- Implemented 5 level paging (based on SV57)
- Implemented some degree of interrupts (though not fully adhering the spec yet)
