feat(tvix/nix-compat): introduce parsing for Nix Hash strings r/5880

We ironically didn't add support parsing for the "native" format that
Nix uses under the hood.

This extends the from_str method to peek at the prefix of the string to
determine whether to try decoding as SRI, Nix string, or whether it
should be a bare digest.
