This PR completely removes the pyarrow dependency and uses the new PyCapsule protocol to transfer data from a python layer (in this case the python library
arrow_python_nocopy
) to the c++ layer (in this case a C++ library calledlibarrow-python-nocopy.so
) entirely over the C API without any weird hackery (e.g. finos/perspective#1157 (comment))
