Add support for PyBind11 #1517
Description
Hi,
for several projects, I made Python bindings with PyBind11 and I needed to be able to pass back and forth Pinocchio objects. I have a slightly different implementation in each project, which is not very clean.
As people usually prefers PyBind11 to Boost, I think it is reasonable to have in this project one header which contains everything one needs to do the conversions. Another reasonable option is to use a repo (e.g. pinocchio-pybind11) for this, although, if it is a single header, I'm not sure it's worth it.
I can implement this (with a low bandwidth but there is no emergency) if we agree (and if it does not exists already).
