[TIMEPIX] Add support for Timepix4
Description
This change is to fully support the next detector generation (Timepix4). Therefore a small change to timewalk correction needs to be implemented
By adding a new parameter timewalk_tot_step_ns (default 25, as before hardcoded), describing the time over threshold increment between entries in the timewalk lookup tables, the higher resolution (1.5625 ns) of the Timepix4 chip can be also used for timewalk correction.
