Title: WIP Fix error: Namespace prefix m on math is not defined

Note: Please do not merge.

I've created a string manipulation function `fixup_cnxml` to try to remove the error before we use lxml.etree. Is this the right place to fix this?

I have thought of two ways to fix "Namespace prefix m on math is not defined":
- as below, remove the prefix
- add "xmlns:m="http://www.w3.org/1998/Math/MathML" to .

I don't really know what's right. They give different html outputs.
