olympia_derive currently provides one derive macro, OlympiaInstruction.
A usage example for a two argument instruction is below:
```rust
opcode=0x00AA_A111,
label="LD",
excluded(0b1010_1100)
)] struct LoadRegisterConstant8 { #[olympia(dest, mask=0xA)] dest: ByteRegisterLookup, #[olympia(src)] src: u8, } ```
A usage example for one argument instruction is below:
```rust
opcode=0x110A_A000,
label="RET",
)] struct ReturnIf { #[olympia(single, mask=0xA)] dest: ByteRegisterLookup, } ```
A usage example for no argument instruction is below:
```rust
opcode=0x1100_1001,
label="RET",
)] struct ReturnIf; ```
