typing: matchers and senders

Leftover error that I cannot fix:

* https://github.com/python/mypy/issues/708

Leftover error that I am unsure of what to do:

* xml handlers are not properly typed

(it seems like nothing in slix is using it, considering a removal
 instead of adding an Union everywhere)
