Standardize the way that memory values are handled

Chris-Johnston commented 6 years ago

Lot of general refactoring and code cleanup. Standardizing the way that memory values are dealt with, instead of converting back and forth from bytearrays in multiple ways.

Makes a MemoryValue type which can be used to convert to and from different types. This requires a rewrite of a lot of things. Little to no changes are made to the logic and flow, however the interfaces and return types of many commonly used functions have been changed. A lot of the tests have to be rewritten for this new interface, but they are still testing the same functionality.

Still need to:

[x] Update the opcodes to use the MemoryValue for math operations
[x] Address how I'm going to deal with CCR using MemoryValue
[x] Add support for logical and arithmetic shift left/right

This PR has been blocked by a lack of time commitments, will work on when I become more available.

Okay, finally got the tests to pass again. All that's left

[x] Clean up the code
[x] Remove any debugging print statements
[ ] Seek review & refactor the code w/ fresh eyes.
