Title: Fix XLSX file corruption when saving an existing file containing images

I have a situation where I am using an existing XLSX file as a template. The single sheet in this file contains an image (OneCellAnchor). The resulting file was becoming corrupt when I opened, modified, and saved it.

I noticed a few of the parse conditions for CT_OneCellAnchor and CT_AbsoluteCellAnchor are incorrect.
