Zone labels incorrect for femur

[kaitlynstiles]

Describe the bug
Zone three is labeled as "area of the cranial attachment," which does not make sense. It should be something like "lateral portion of proximal metaphysis." I know that this is not the only bone with zone labels that do not match the zone they are describing. We need to go through and correctly label the zones based on human anatomical features. The original zonation article was developed based on animal zones and the terminology does not always translate well.
