[TIMEPIX] Add a time of arrival offset option as a parameter

Description

Data shows particular rows which are shifted in timing by 25 ns - the occurrence of the shift depends on the data acquisition method. It varies between different detectors. The required offsets are provided as stdout by Serval. The implementation now accepts 1d arrays that can be copied directly from that output.

How Has This Been Tested?

This has been tested with a reference run on maxwell. (p900421, 307) Python 3.8.18.
