Ubuntu 18.04 is now in "Extended Security Maintenance", but otherwise
gets no updates. Remove it from supported distributions (regarding
installing packages); users can of course still use it.
Users are encouraged to upgrade to Ubuntu 20+.
Apart from the obvious change of adding ubuntu24.04 to supported
distributions, we need to remove liblapacke-dev as it is incompatible
with libatlas3-base. Installing both aborts with:
The following packages have unmet dependencies:
liblapacke : Breaks: libatlas3-base (< 3.10.3-14) but 3.10.3-13ubuntu1 is to be installed
It seems that we don't need it though, as liblapacke-dev installs the
right atlas library as a dependency.
* Also added obsolence messages for the old L2 simulator since 2022.w01 EpiSci merge
* Added link to their new tutorial
