This PR:

• makes bump pibind11 #414 obsolete
• addresses phase out setup.py in favour of pyproject.toml #403
• potentially helps with:
  • Add enabling of CAMP for chemistry #368,
  • exception propagation seems not to work on arm64 (failing test_spec_by_name_not_found test on CI) #348,
  • introduce new Matlab compatibility workaround proposed in pybind11 #334,
  • multi-mode dist modes are returned back in reverse order wrt the ctor input #213
  • lack of hyperlinks from type names in docs (since introduction of the _PyPartMC module "hack" for Windows & Python >=3.8); also some function signatures have arg0, arg1 with no types #99
  • pdoc html is missing docstrings for properties (while it works for methods) #413

BTW, the only place where Google indexed seemingly identical error as we have in the codecov build is here: nvidia-isaac/nvblox#73
