update neck cut

This commit updates the neck cut to increase the number of neck PMT hits even
if the neck PMT hit time isn't calibrated correctly. This is because I was
looking at all muon events which didn't have an NHIT trigger fire and I noticed
the following events:

Run    GTID
----   ----
10036  1462054
10040  2270713
10133  1096180

They all appear to be neck events, but the first one in particular has 4 neck
PMTs that got hit. When looking into it I realized that all 4 hits had ept
times of -9999.

several events:
