There should be a seed to select the generic starting value for mass flow reproducibly

[fwitte]

With the random state being completely random, it might not be possible to replicate model runs. Sometimes a model run can crash while the same model rerun works. The first goto for randomness in TESPy would be the selection of mass flow with no better value at hand in: https://github.com/oemof/tespy/blob/f9757d090a038ed5cbf5e65a1c49ed5aa7209e15/src/tespy/networks/network.py#L1808
