Installation with conda hangs

[falkamelung]

Following the installation instructions, it hangs for me in the conda installing isce2 step (linux). The work-around is to install isce2 with mamba but it still takes a few hours. I would recommend to remove as much as possible from the requirements.txt (e.g. the minsar dependencies).

That conda install isce2 did not work (or was too slow) is of course weird. Did I do something stupid? It happened on consecutive days. I I did not investigate as mamba worked fine.
