`imdl torrent dump` produces invalid json

[timbretimber]

Apologies if it's not intended to be valid json but the info.pieces section of the imdl torrent dump is invalid because it's an unquoted string.

intermodal/src/subcommand/torrent/dump.rs

Line 77 in 80cbc3b

Value::Bytes(bytes) => fmt_string(f, bytes)?,

Thanks for the report! Fixed in #566.

It's also very nice to get a normal issue written in a normal human way, and not AI slop. So thanks for that!
