Python3.11 pybindfixes

Description

Could not compile python interface with python3.11. This is fixed by newer pybind11 versions.

@stuko since I don't really know much about pybind it would be greate if you could have a look at this.

Summary of changes

Update pybind11 by including it as git submodule as recommended in the docs. It was necessary to change 2 lines of code from using make_caster::name() to make_caster::name in PythonBinding.h, other changes are due to autoformatting
