This stops using our own custom Hash structure, which was mostly only
used because we had to parse the JSON representation somehow.
Since cl/8217, there's a `NixHash` struct, which is better suited to
hold this data. Converting the format requires a bit of serde labor
though, but that only really matters when interacting with JSON
representations (which we mostly don't).

This only trims the output paths from a Derivation struct, not the
output hashes.

Call this function derivation_or_fod_hash, and return a NixHash.
This is more in line with how cppnix calls this, and allows using
to_nix_hash_string() in some places.

Some of these strings are actually just the nix hash representation of
the hash calculated earlier.
There's another one passed around via calculate_drv_replacement_str, but
that's left for a followup.

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.

Nix accepts SRI hashes that are missing their padding characters
in base64, as seen in
7e49471316/pkgs/development/libraries/kerberos/krb5.nix .
It only seems to work in the SRI case, not with `sha256` being set to a
(nopad) base64 string.
Add regression tests for this, and document why we don't want to support
*additional* characters afterwards.

Instead of implementing `std::fmt::Display for Derivation` and relying
on the `to_string` method, introduce a `to_aterm_string()` method, which
does the same thing, but makes it clearer what we're producing, rather
than just calling `to_string()``.

Move the Derivation struct definiton up into `src/derivation/mod.rs`,
