Introduce PTOT mode parameter instead of dedicated scans

ITkPixV1 needs the Precision TOT feature in order to recognize all hits. We added dedicated _ptot scans. Since this will blow up our number of scans (basically for every scan with ITkPix the Precision TOT feature is needed), it would be better to just introduce a variable like use_ptot , which enables the precision tot feature for ITkPixV1 and just does nothing in case of RD53A.

Required changes:

1. Change _configure() step in order to enable PTOT:

if bench_config['use_ptot']:
    self.chip._enable_col_precision_tot(range(0, 54))
    self.chip.registers['ToTConfig'].write(int(format(12, '04b') + format(ptot_del, '09b'), 2))
    self.chip.registers['TriggerConfig'].write(20)

2. Change scan():

• Change mask_pattern and shifted masks (need PTOT pattern + shift also hitbus mask)
• Change latency: @mstandke why?
• Add add_ptot_table_data() (needed for proper raw data interpretation)

These changes have to be done for every scan, but especially 2. changes the scan() a lot. Maybe a general scan_loop() can help us here?
