alternative method for finding the time delays for broken GPS periods. It is much faster: running on 6 subruns, it took 12 min for the original method and 2 min for this one. For most of the subruns the results are similar

the first two subruns have no proper time delays computed in neither the original method nor this one. subrun 62 is the only one in which there is significantly less events matched with the new method is also problematic - running only over it the times are not matched properly with neither of the methods
