All of these occurences are actually sha256 digests of some fingerprint
- which means there's not a lot of need to do the hashing outside.
Instead of passing in a digest, keep the sha256 hasher in the function,
and pass in a fingerprint.
This makes it much easier to construct fingerprints using format!() in
all consumers, because we need don't need to juggle with the hasher
anymore.

Different to the go-nix implementation, we don't have a custom "writing
mode" where output paths are omitted from output, but we simply run the
serialization with these fields unpopulated (during construction).
This means, there's no need for a custom writing mode that strips
outputs, so we can drop the comments.

When constructing derivations inside builtins.derivationStrict, we'd
have to very frequently check whether certain outputs have already
been inserted into the derivation inputs.
Using a set type is much easier, especially as this has to be ordered
and the source data that is being inserted also comes from a set,
which might let us pass this more efficiently in the future.
Note that the validate function no longer checks the order of the
entries, as that is now guaranteed by the type.

This exercises the output path calculation functions like a constructing

It first assembles the bar derivation, does the output path calculation
on it, then continues with the foo derivation.

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
