This gives a 1.23 speedup on transformers-extras. We could change to
msgpack for the entire cache if we want. I only tried this format and
postcard so far, where postcard was much slower (like 1.6s).
I don't actually want to merge it like this, i wanted to figure out the
ballpark of improvement for switching away from json.
```
hyperfine --warmup 3 --runs 10 "target/profiling/puffin pip-compile --cache-dir cache-msgpack scripts/requirements/transformers-extras.in" "target/profiling/branch pip-compile scripts/requirements/transformers-extras.in"
Benchmark 1: target/profiling/puffin pip-compile --cache-dir cache-msgpack scripts/requirements/transformers-extras.in
Time (mean ± σ): 179.1 ms ± 4.8 ms [User: 157.5 ms, System: 48.1 ms]
Range (min … max): 174.9 ms … 188.1 ms 10 runs
Benchmark 2: target/profiling/branch pip-compile scripts/requirements/transformers-extras.in
Time (mean ± σ): 221.1 ms ± 6.7 ms [User: 208.1 ms, System: 46.5 ms]
Range (min … max): 213.5 ms … 235.5 ms 10 runs
Summary
target/profiling/puffin pip-compile --cache-dir cache-msgpack scripts/requirements/transformers-extras.in ran
1.23 ± 0.05 times faster than target/profiling/branch pip-compile scripts/requirements/transformers-extras.in
```
Disadvantage: We can't manually look into the cache anymore to debug
things
- [ ] Check more formats, i currently only tested json, msgpack and
postcard, there should be other formats, too
- [x] Switch over `CachedByTimestamp` serialization (for the interpreter
caching)
- [x] Switch over error handling and make sure puffin is still resilient
to cache failure
