Implement full instruction set virtual machine

This is a full list of changes that need to be made to the virtual machine.

Each task will likely be made into an issue of its own right.

[ ] Call Stack
- Gonna ditch the Stack structure and replace it with a CallStack struct.
- Also need to add CallFrames and just get everything set up properly
[ ] Instruction Buffer
- Ditching the Buffer struct for InstructionBuffer struct
- This will be more specific while also having some better features (hopefully)
[ ] Registers
- I want registers to be on the stack, so they're probably going to be a basic array
[ ] Variable Pools
- These need to be set up properly
- Variables should already be mangled by the assembler by the time we get them
[ ] Block Handler
- Needs to find the .data, .meta, and .code blocks
- Use .meta data for configuration
- Use .data data to set up variables, constants, and structs
[ ] Error Handler
- Basic error handling, use r8 and r9.
[ ] Implement all the methods needed for each instructions
