[Bug 2048760] [NEW] [MIR] python-cssselect

[Lukas Märdian]

Public bug reported:

lxml grew a new Recommends on python3-cssselect, that leads to a new
component-mismatch in Ubuntu.

Apparently "cssselect" was split out of lxml back in 2012 (https://lxml.de/3.0/changes-3.0alpha1.html).
It was developed in parallel since then.

According to this bug report (https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=1017067), it is not really an optional dependency,
but rather crashes if cssselect is not installed. So we should either:

1/ MIR python-cssselect (and make it a real "Depends")
   => Seems plausible, as cssselect is a leaf package, without further dependency, providing test coverage.
2/ Change lxml to make cssselect an actually optional dependency, and downgrade it to "Suggests"
