refactor(tvix/derivation): make output hashes an Option<Hash> r/5589
This conveys better if an output of a Derivation is fixed-output or not,
and provides a Hash struct that can be used to store the algo and
digest.

In case it's not, this can simply be None. The serde field attributes
have been updated to still accept the same JSON.

We currently still store the hash algo and digest as strings, mostly
because the only thing populating it so far is the example JSONs.
We might want to update this, once actual Nix code populates this.

While updating write.rs, I pushed some of the Vec<String> to [&str]
conversions inline, and made it a Vec<&str>, because it was annoying to
juggle with.
