Remove the parser I wrote in favor of Konsti's which is much more
complete. The only change vs. the version in `poc-monotrail` is that I
changed the tests to use insta rather than manually storing and
comparing against JSON snapshots.
Closes https://github.com/astral-sh/puffin/issues/89.
Mocks out the PyPI client using some checked-in fixtures. The test is
very basic, and I'm not very happy with all the ceremony around the
mocks and such, but it's an interesting experiment at least.
When we go to install a locked `requirements.txt`, if a wheel is already
available in the local cache, and matches the version specifiers, we can
just use it directly without fetching the package metadata. This speeds
up the no-op case by about 33%.

This PR gets `gourgeist` passing our local CI and integrated into the
broader workspace.
There's some duplicate between concepts in `gourgeist` (like the
`InterpreterInfo`) and structs we have elsewhere, but we can tackle
those later.
This PR massively speeds up the case in which you need to install wheels
that already exist in the global cache.
The new strategy is as follows:
- Download the wheel into the content-addressed cache.
- Unzip the wheel into the cache, but ignore content-addressing. It
turns out that writing to `cacache` for every file in the zip added a
ton of overhead, and I don't see any actual advantages to doing so.
Instead, we just unzip the contents into a directory at, e.g.,
`~/.cache/puffin/django-4.1.5`.
- (The unzip itself is now parallelized with Rayon.)
- When installing the wheel, we now support unzipping from a directory
instead of a zip archive. This required duplicating and tweaking a few
functions.
- When installing the wheel, we now use reflinks (or copy-on-write
links). These have a few fantastic properties: (1) they're extremely
cheap to create (on macOS, they are allegedly faster than hard links);
(2) they minimize disk space, since we avoid copying files entirely in
the vast majority of cases; and (3) if the user then edits a file
locally, the cache doesn't get polluted. Orogene, Bun, and soon pnpm all
use reflinks.
Puffin is now ~15x faster than `pip` for the common case of installing
cached data into a fresh environment.

This PR modifies the `install-wheel-rs` (and a few other crates) to get
everything playing nicely. Specifically, CI should pass, and all these
crates now use workspace dependencies between one another.
As part of this change, I split out the wheel name parsing into its own
`wheel-filename` crate, and the compatibility tag parsing into its own
`platform-tags` crate.
This PR modifies the PEP 440 and PEP 508 crates to pass CI, primarily by
fixing all lint violations.
We're also now using these crates in the workspace via `path`.
(Previously, we were still fetching them from Cargo.)
