Make dora cli pip installable (#706)

This PR makes dora-cli pip installable with

```bash
pip install dora-rs-cli
```

This is a pretty big deal to make pre-compiled dora-cli easily available
in China, where pip is widely mirrored

It fixes some abi3 issues from #695 such as not being a cdylib and
python project.
