refer to crate and nix-compat with the same name so that the generated

In essence `use nix_compat::nix_daemon:🇩🇪:NixDeserialize` is an error

This moves the URL component parsing code we had in nar-bridge to
nix-compat.
We change the function signature to return an Option, not a
Result<_, StatusCode>.
This allows returning more appropriate error codes, as we can
ok_or(…) at the callsite, which we now do: on an upload to an
invalid path, we now return "unauthorized", while on a GET/HEAD, we
return "not found".
This also adds support to parse compression suffixes. While not
supported in nar-bridge, other users of nix-compat might very well want
to parse these paths.
Also fix the error message when parsing NAR urls, it mentioned 32, not
52, which is a copypasta error from the narinfo URL parsing code.

Similar to how cl/12253 already did this for `Signature`, we apply the
same logic to `StorePath`.
`StorePathRef<'a>'` is now a `StorePath<&'a str>`, and there's less
redundant code for the two different implementation.
`.as_ref()` returns a `StorePathRef<'_>`, `.to_owned()` gives a
`StorePath<String>` (for now).
I briefly thought about only publicly exporting `StorePath<String>`
as `StorePath`, but the diff is not too large and this will make it
easier to gradually introduce more flexibility in which store paths to
accept.
Also, remove some silliness in `StorePath::from_absolute_path_full`,
which now doesn't allocate anymore.

Requiring `name` to be a `&str` means it'll get annoying to pass around
`Signature`, but being able to pass them around in an owned fashion is
kinda a requirement for a stronger typed `PathInfo` struct, where we
want to have full ownership.
Rework the `Signature` struct to become generic over the type of the
`name` field. This means, it becomes possible to have owned versions
of it.
We don't want to impose `String` or `SmolStr` for example, but want to
leave it up to the nix-compat user to decide.
Provide a type alias for the existing `&str` variant (`SignatureRef`),
and use it where we previously used the non-generic `Signature` one.
Add some tests to ensure it's possible to *use* `Signature` with both
`String` and `SmolStr` (but only pull in `smol_str` as dev dependency
for the tests).
Also, add some more docstrings, these were a bit sparse.

Even if we have an aligned (or zero) size (and thus have no padding),
we may still have a non-padding trailer.
Since an exact read of only the user data bytes must always read the
trailer bytes as well, this has to happen for aligned sizes too.
For zero-sized trailers, we solve this by reading immediately, since no
read is required of the user at all.
user_len thus becomes a NonZeroU64, and the definition of "body data"
is adjusted to always exclude the final block.
