Add a node similar to the STL import node (d1455c4138) that
imports OBJ files, including both meshes and curves. The output consists
of a geometry instance for each mesh/curve in the file.
There are a few improvements to address in the future: Currently the node
has no inputs besides the file path. Options may be exposed in the future.
Materials are also not imported yet, because creating material data-blocks
during evaluation may not be trivial.
