It looks like Cargo, notice the bold green lines at the top (which
appear during the resolution, to indicate Git fetches and source
distribution builds):

Closes https://github.com/astral-sh/puffin/issues/287 although we can do
a lot more here.
There are packages such as DTLSSocket 0.1.16 that say
```toml
[build-system]
requires = ["Cython<3", "setuptools", "wheel"]
```
In this case we need to install requires PEP 517 style but then call setup.py in the
legacy way
Part of making home-assistant work
Select a compatible wheel for a version, even we already found a source
distribution previously.
If no wheel is found, select the most recent source distribution, not
the oldest compatible one.
This fixes the resolution of `mst.in`, which i added
This is also a lot faster. Unfortunately it copies a lot of code from
the sync cli since the `Printer` is private.
The first commit are some refactorings i made when i thought about how i
could reuse the existing code.
## Summary
This PR enables the proof-of-concept resolver to backtrack by way of
using the `pubgrub-rs` crate.
Rather than using PubGrub as a _framework_ (implementing the
`DependencyProvider` trait, letting PubGrub call us), I've instead
copied over PubGrub's primary solver hook (which is only ~100 lines or
so) and modified it for our purposes (e.g., made it async).
There's a lot to improve here, but it's a start that will let us
understand PubGrub's appropriateness for this problem space. A few
observations:
- In simple cases, the resolver is slower than our current (naive)
resolver. I think it's just that the pipelining isn't as efficient as in
the naive case, where we can just stream package and version fetches
concurrently without any bottlenecks.
- A lot of the code here relates to bridging PubGrub with our own
abstractions -- so we need a `PubGrubPackage`, a `PubGrubVersion`, etc.
