parallelization block fixed setup

• setting the minimum number of required cores by the maximum of all settings

Could you add maybe two sentences on what was wrong before? And how it is fixed in this PR? Just to make sure that we don't create problems on other ends of the parallelization logic. :)

Other than that: Seems to work, great! 💯

Before the program checked for the minimum number of cores required to run by looking also at the minimum number of cores requested in the configuration, which is of course illogical. It should be the maximum number of cores requested, which led to the problem:

If refine requests 2 cores and postprocessing requests 4, the program will set up the blocks considering 2 cores as the minimum requirement, which possibly leads to postprocessing jobs not launching indefinitely due to being blocked by resource management (blocks only have 2 cores available).

Makes sense. Thanks for your contribution!
