py-lxml: updated to 4.2.0

4.2.0:
Features added
* SelectElement.value returns more standard-compliant and browser-like defaults \ 
for non-multi-selects. If no option is selected, the value of the first option \ 
is returned (instead of None). If multiple options are selected, the value of \ 
the last one is returned (instead of that of the first one). If no options are \ 
present (not standard-compliant) SelectElement.value still returns None.
* The HTMLParser() now supports the huge_tree option. Patch by stranac.

Bugs fixed
* Some XSLT messages were not captured by the transform error log.
* Crash at shutdown after an interrupted iterparse run with XMLSchema validation.
