I make a pull request here, so the Github-CI runs on this branch. Otherwise I'd have to modify the CI settings.

Before merging, the commit marked "TMP" needs some changes. Moving stuff to the right files. Maybe merging with the final commit or reordering.
There are some unfinished proofs (well-foundedness of lt_cardinal).

And adapt the proofs as necessary.

Also, split proof of 2.countability of `RTop`.

The fact that a countable subbasis implies 2. countability and the fact
that the rays in ℝ starting at rational numbers form a subbasis might be
used in other situations as well.
The proof is incomplete, because it needs `le_cardinal_ens_wf`.
Adds files `ZornsLemma/FunctionPropertiesEns.v`,
`ZornsLemma/CardinalsEns.v` and an alternate notion of cardinality for
`Ensemble`.
