Sorting Issue: pulse_id and Time Become Misaligned After Sorting

[zhut19]

I tried to simulate a scenario where digitizers are triggered externally by forcing pulse windows across channels to start simultaneously. However, I encountered misalignments in the digitization process. Specifically:

In this section, propagated_photons are no longer ordered in time afterward, as the default quick sort won't preserve the original order when the compare is the same.
In this section, that pulse_groups is not sorted by pulse_id, leading to a mismatch between elements in pulse_groups and photons.
