* Update instruction set to match final specificationBen Bridle2024-09-07

* Improve efficiency of some instructionsBen Bridle2024-09-03
| | | | | | | | When a value is to be read and kept on the stack, instead of popping and immediately pushing it we now use a more efficient `get` stack method. The pop_u16 stack method has also been changed to a variation that assembles to fewer CPU instructions.
* Remove trailing semicolons in stack macrosBen Bridle2024-08-30
| | | | The compiler warned that these are a deprecated syntactic form.
* Fix SHF instructionBen Bridle2024-05-18
| | | | | | | The wrong shifting operation was being used for the SHF operation. The 'wrapping' operations were shifting by the given distance, modulo eight, which was yielding incorrect results for shift distances greater than seven.

* Change processor code to match updated Bedrock specificationv2.0.0Ben Bridle2024-01-20
