Windows path issue

Hey hey - don't know if this is worth the whole finangle of a github pull request that will most likely get rejected, but I'm getting errors on Windows (I know, | know) with enhance.

It mangles paths with drive letters because of line 143 in _get_elements.mjs. Changing it to readFileSync(e) rather than readFileSync(fileURL.pathname) fixes it, but it might break other things. 

Just thought I'd let you know ;-)

I added a test case, but I can't reproduce it. I will follow up with a poster for more details.
