update muon cut
This commit updates the muon cut to require at least 1 OWL hit which has a high
charge and is early relative to nearby normal PMTs. This replaces the previous
cut criteria which required 2 OWL hits to be early relative to the 10%
percentile of all the normal PMT hits.
This new cut should target external muons better although I still need to do
some testing. In the future I'd like to optimize the distance at which PMTs are
considered nearby. Currently I just use 3 meters which seemed like a good value
based on some initial testing.
