This allows calling validate() on a derivation that doesn't have its
output paths already calculated yet. It allows offloading some of the
error checking in builtins.derivation* to be offloaded to that function.

This uses the exposed StorePath::validate_name method to check for other
invalid output names (for which it would not be possible to construct a
store path of).

`drv` is an invalid output name too, as this would cause a
`builtins.derivation` call to return an attrset with a `drvPath` key
(which already exists) and has a different meaning.
Also handle errors during store path construction, and return our own
error type, instead of the ParseStorePathError.

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.

Some of the fields in a Derivation struct stay empty, and manually
creating BTreeMap or vec for it is annoying.
Derive Default instead, so we can use the defaults instead of writing
more by hand.

This project was not previously covered by CI (fixed in this commit),
so we didn't catch breakage due to a renamed module.
This was noticed while rebasing a CL that has a dependency on this
crate in its Nix build.

This exercises the output path calculation functions like a constructing
client (an implementation of builtins.derivation) would do.
It first assembles the bar derivation, does the output path calculation
on it, then continues with the foo derivation.
The code ensures the resulting Derivations match our fixtures.

This will return the fixed output of a derivation (and its hash), or
None if the Derivation is not fixed-output.
It will simplify the logic in the output path calculation a bit.

Use the #[serde(rename = "…")] field attributes to match the field names
that Nix uses in its JSON output (nix show-derivation).
This allows us to just re-use the exact same fixtures from go-nix,
without manual post-massaging.

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.
