This function is called when a Service 3 Housekeeping packet is received.
Please note that the object IDs should be compared by value because direct comparison of
enumerations does not work in Python. For example use:
if object_id.value == ObjectIds.TEST_OBJECT.value
to test equality based on the object ID list.

The first list contains the header columns, the second list the list with
the corresponding values. The bytearray is the validity buffer, which is usually appended
at the end of the housekeeping packet. The last value is the number of parameters.
