Add default / expected values to status registers
To allow checks if the chip is working as expected add default (expected) values for both pixel and peripheral status registers. Currently the values are just read out and printed: https://gitlab.cern.ch/cms-etl-electronics/module_test_sw/-/blob/master/tamalero/ETROC.py?ref_type=heads#L200 The function could also return a True/False value depending on whether all registers are returning expected values. As an example, default values for configuration registers are defined like here: https://gitlab.cern.ch/cms-etl-electronics/module_test_sw/-/blob/master/address_table/ETROC2_example.yaml?ref_type=heads#L19
