Added and refactored several instructions and memory operations, improving accuracy and functionality for emulation. Introduced new dependencies (`serde_json`, `glob`) and submodule for test framework integration. Enhanced debugging, flat RAM handling, and opcode parsing while fixing multiple calculation and flag-setting issues.
This commit sets up a foundational CPU simulation with registers, a memory bus, and an initial instruction set implementation in Rust. It includes operations like ADD, SUB, AND, and bit manipulations, as well as basic project configurations through Cargo and IDE settings.
