It looks like using _either_ async Rust with a `JoinSet` _or_
parallelizing a fixed threadpool with Rayon provide about a ~5% speed-up
over our current serial approach:
```console
❯ hyperfine --runs 30 --warmup 5 --prepare "./target/release/puffin venv .venv" \
"./target/release/rayon sync ./scripts/benchmarks/requirements-large.txt" \
"./target/release/async sync ./scripts/benchmarks/requirements-large.txt" \
"./target/release/main sync ./scripts/benchmarks/requirements-large.txt"
Benchmark 1: ./target/release/rayon sync ./scripts/benchmarks/requirements-large.txt
Time (mean ± σ): 295.7 ms ± 16.9 ms [User: 28.6 ms, System: 263.3 ms]
Range (min … max): 249.2 ms … 315.9 ms 30 runs
Benchmark 2: ./target/release/async sync ./scripts/benchmarks/requirements-large.txt
Time (mean ± σ): 296.2 ms ± 20.2 ms [User: 36.1 ms, System: 340.1 ms]
Range (min … max): 258.0 ms … 359.4 ms 30 runs
Benchmark 3: ./target/release/main sync ./scripts/benchmarks/requirements-large.txt
Time (mean ± σ): 306.6 ms ± 19.5 ms [User: 25.3 ms, System: 220.5 ms]
Range (min … max): 269.6 ms … 332.2 ms 30 runs
Summary
'./target/release/rayon sync ./scripts/benchmarks/requirements-large.txt' ran
1.00 ± 0.09 times faster than './target/release/async sync ./scripts/benchmarks/requirements-large.txt'
1.04 ± 0.09 times faster than './target/release/main sync ./scripts/benchmarks/requirements-large.txt'
```
It's much easier to just parallelize with Rayon and avoid async in the
underlying wheel code, so this PR takes that approach for now.

Reimplementation of wheel installing in rust. Supports both classical venvs and monotrail.
There are simple python bindings:
from install_wheel_rs import LockedVenv
locked_venv = LockedVenv("path/to/.venv")
locked_venv.install_wheel("path/to/some_tagged_wheel.whl")
and there's only one function: install_wheels_venv(wheels: List[str], venv: str), where wheels is a list of paths to wheel files and venv is the location of the venv to install the packages in.
See monotrail for benchmarks.
