Automate finding vanadium for MARI

[Pasarus]

Having had a discussion with our contact on MARI, we came to the conclusion that it may be possible to go find the latest vanadium run, by checking the title for "van", "30mev", and "50hz". The latest run with those in the title should be our vanadium run to use for processing data. Maintain a default using the current value that is set manually. This would have worked for the following:

cycle_24_1: 29526
cycle_24_2: 29680
cycle_24_3: 29895

Example psuedo/python code:

if "van" in title.lower() and "30mev" in title.lower() and "50hz" in title.lower() and experiment_number is None:
    # Is latest vanadium run
