A crate for encoding and decoding eBPF instructions.

## Usage

```rust
use bpf_ins::{Instruction, Register};

//
// return 0
//
let instructions = [
    Instruction::mov32(Register::R0, 0), // mov r0, 0
    Instruction::exit(),                 // exit
];

let mut encoded = vec![];
for instruction in &instructions {
    let (x, y) = instruction.encode();
    encoded.push(x);
    if let Some(y) = y {
        encoded.push(y);
    }
}
```
