Add pytypes in vendor directory

Using:

```
pytypes @ git+ssh://git@github.com/Stewori/pytypes@b7271ec654d3553894febc6e0d8ad1b0e1ac570a
```

in `install_requires` forbid the package to be
correctly installed.

So we vendored the `pytypes` package waiting for
an official package version supporting python 3.7+
