Parse pip cache dir

It can happen that we find a pip cache directory in a codebase. It contains both code archives and JSON that would be useful to parse and collect.
For instance:
```$ less .cache/pip/wheels/eb/60/37/ee40403cbd895ccdb57eb28b03b0afabeb449d5df9ce776a0d/origin.json
pombreda@computer4:~$ ll .cache/pip/wheels/eb/60/37/ee40403cbd895ccdb57eb28b03b0afabeb449d5df9ce776a0d/
total 80
