[syjcnss]

Problem

The find-program-derived-address command doesn't print the bump seed, which could be useful.

$ solana find-program-derived-address -v 11111111111111111111111111111111 "string:HELLO"
Seeds: [[72, 69, 76, 76, 79]]

Thanks for your contribution! It looks good to me -- there's just a clippy issue to resolve, then we should be able to merge this.

clippy is complaining about the &Vec passed in, and saying to change that to &[_] instead: https://github.com/anza-xyz/agave/actions/runs/11114470308/job/31517664360?pr=3042#step:5:1336

And then this will need to change to seeds.to_owned()
