Measure font size

Use of a font size smaller than 10 points should lose a form points. Using a font size larger than 14 points should be flagged as well.

Note that average populations can read printed text at 10 points at 184 wpm, so it's likely not too small. https://iovs.arvojournals.org/article.aspx?articleid=2166061

Potential starting point:

• do the same hook into PDF miner to get the text boxes, and then calculate how much of the page that particular text box covers on the page. The output would be a dict of font sizes (and font face name), each associated with a percentage of the page.

Should be between 9 and 18pt for the body of the text.
