Update restG4 to condor script

[lobis]

In this PR I update the current restG4toCondor.py with the version I am currently using which should serve the same goal as the current script but is implemented in a different way. Since they both serve the same purpose I replaced the current script with this one but it could be argued to keep both versions.

Usage example:

python3 restG4ToCondor.py --rml simulation.rml --n-jobs 10 --output-dir /path/to/output/dir --time 1h

The script has some specific named arguments such as --rml or --n-jobs and then will forward all other arguments directly to restG4 (for example the --time argument in this example).

It automatically creates directories with the timestamp of the simulation and all log files which helps with organization.

Currently this script assumes the user is working on NAF-IAXO and stores data in the nfs directories (for which the user needs to have permissions to their own user directory).
