Expanding nSort and Patch arguments

[Patrick de Perio]

(Simple task for anyone wanting to get more familiar with the workflow.)

Need to add "-s" argument to run_sim.sh here:
https://github.com/XENON1T/processing/blob/master/montecarlo/run_sim.sh#L125

nSort arguments documented here:
https://github.com/XENON1T/mc/blob/master/nSort/nSort.C#L21

As well as more flexibility for PATCHTYPE argument, which has been expanded according to Table 2 here:
https://xecluster.lngs.infn.it/dokuwiki/doku.php?id=xenon:xenon1t:sim:notes:marco:xenon1t-tips-for-mc-production#running_the_patch_scripts

Need to decide whether it should be a command line argument to run_sim.sh (for e.g. mc_process.py grid submission), or just modified locally by user for each configuration.
