We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Changed pypiwin32 to pywin32
### What was wrong?
pypiwin32 is just an empty package requiring pywin32, so this can just be required directly. As far as I know, pypiwin32 is only there for historical reasons.

Related to Issue #1721

### How was it fixed?
change it in setup.py

### Todo:
- [ ] Add entry to the [release notes](https://github.com/ethereum/web3.py/blob/master/newsfragments/README.md)
