I'll merge early, but I want to see the all token tests run here or locally first

Just checked - all other instances of .split_at() in this repo have length checks before calling split_at()

twotx CI failure is known and unrelated

As a follow-up, perhaps something more exhaustive?

    #[test]
    fn test_instruction_unpack_panic() {
        for i in 0..255u8 {
            for j in 1..10 {
                let mut data = vec![0;j];
                data[0] = i;
                let _no_panic = TokenInstruction::unpack(&data);
            }
        }
    }

Yep, on my list already :)

I am fuzzing it with

    #[test]
    fn test_instruction_unpack_fuzz() {
        for _ in 0..10000000 {
            let r: usize = rand::thread_rng().gen_range(0..10);
            let data: Vec<u8> = (0..r).map(|_| rand::thread_rng().gen()).collect();
            _ = TokenInstruction::unpack(&data);
        }
    }
