README: comparison with openapi-python-client

[vgavro]

Would you consider adding comparison to docs with this project https://github.com/openapi-generators/openapi-python-client ? It's also using Pydantic and looks like having the same goals as yours, while it's older, it would be really useful to understand the pros of this project to use, because obviously it was created because the project above didn't meet some of your requirements.
Thanks for reply!

This project has been very much an exercise for me that i provided for a larger community. The project you linked is of course very similar, however the largest difference is surely the usage of pydantic in the generated code, afaik the one you linked uses dataclasses for similar purposes.

If you'd like to work out all the other differences, i am happy to accept a pull request to the README.md :)
