Replace imgmath by mathjax sphinx-extension

[jlaehne]

Requirements

As brought up in #166, math is not rendering any more in the ReadTheDocs. AS brought up by @hakonanes in https://github.com/hyperspy/hyperspy/pull/3050#issuecomment-1386765990 sphinx.ext.mathjax should be working, while sphinx.ext.imgmath seems to be broken (in both HyperSpy and LumiSpy). Therefore replacing the extension.

Fixes #166

Progress of the PR

• [x] Change implemented (can be split into several points),
• [x] added line to CHANGELOG.md,
• [x] ready for review.

@jlaehne, do you want to squash the last 2 commits?

I just performed a squash and merge, I think a single commit including changelog is enough for this small change.
