GameBoy ROM parser

A parser to get data out of GB ROMs and perform basic validation. It provides a streaming opcode parser as well as high-level types for inspecting the Gameboy ROM's header.

Demonstration

cargo run --bin gb2json --features="serde_json" -- /path/to/rom/data
cargo run --bin gbstats -- /path/to/rom/data

And here's it in use in a real emulator (rusty-boy).
