* New BuildRequires: pkgconfig(openssl)
* Add MicroTeX as separate tarball: this is missed by upstream git as a submodule, so obs_scm _service's `enable_submodules` is unable to include it either.
* Drop cadabra2-default-python-path.patch: no longer needed after changes to upstream logic for finding python.
