Non-integer font sizes

[ThomasProctor]

version: 1.1.2

I have multiple documents (which, unfortunately, I'm not able to share directly) that I can open just fine in word, but when I try to access a run.font.size on a certain cursed run, I get an error like this: ValueError: invalid literal for int() with base 10: '36.56250317891439'

Here's a full traceback:

I'm guessing this is something similar to an earlier issue, #1335, where the XML schema says this is invalid but there must be some way it ends up happening, but it doesn't break Microsoft Word. Given that this int is being instantly converted to a float, it seems likely that it will be completely harmless to just change int to float on docx/oxml/simpletypes.py:265
