Import part of axioms from HANCESTRO

[anitacaron]

I've reviewed both the HANCESTRO import and resulting afpo-edit.ofn files. I note that the part_of relation between the regions and Africa didn't make it into the import but given that we only import African regions, this isn't the end of the world (could fix in future import). Transfer of AfPO native axioms looks good. No blockers from my side.
