Implementation of the asyncio consumer

Hi, I implemented the asyncio consumer in a similar way as the producer. All missing async functions provided by the C++ library are now implemented in the pybind11 classes and I use futures in python to convert the functions with callbacks to async functions. The reason I started with this implementation is because I need the async consumer in a project with FastAPI myself. Tests could be a little bit patchy, for that reason i would appreciate help if i missed something

Could you also make the tests pass for Python 3.8? Though Python 3.8 will reach EOL on the next month (2024-10)

I will try to fix the issues this week.

I found another issue with the schema system in my asyncio implementation, i will fix this too before the next commit.

Let me fix the broken CI first

Could you rebase to master to resolve the conflicts and have the CI fixed?
