Add a extract_hugr method to extract regions into owned Hugrs.

Closes #1171.

Looks good to me 👍

Would it be poor Rust-taste to do this by implementing Into? I guess this is consistent with extract_subgraph(), otherwise I would have suggested to_hugr() or something like that

We have many ways of obtaining a hugr from a view (there's base_hugr already), so I prefer to keep the explicit method to disambiguate.
