Export Display for Script

[rustaceanrob]

The rust-bitcoin type has a nice feature where the human-readable OP-codes are printed when using the Display version of ScriptBuf. Some users might find this interesting, as this is a feature of the almighty Sparrow wallet.

To see for yourself:

let mut output = String::new();
addr.fmt_asm(&mut output).unwrap();
println!("{output}");

Which should have an output similar to this for a fully built out example:

OP_0 OP_PUSHBYTES_20 1cd30fcc6cc9793c08a1105893c6d1e584a57e48
