This is a new op system that will eventually replace `#[op]`. Features - More maintainable, generally less-coupled code - More modern Rust proc-macro libraries - Enforces correct `fast` labelling for fast ops, allowing for visual scanning of fast ops - Explicit marking of `#[string]`, `#[serde]` and `#[smi]` parameters. This first version of op2 supports integer and Option<integer> parameters only, and allows us to start working on converting ops and adding features.
