1. DeviceInstanceMapper: do not skip devices with inputDeviceError …

   I have a bunch of non-pushbuttons switches connected to some of my
   Lunatone DALI-2 MC pushbutton couplers. These devices unfortunately
   set the "inputDeviceError" bit whenever any of its inputs is
   closed/shorted for longer than T_stuck.
   
   The 62386-301:2017 says (Table 4, page 15) that this timer is up to
   255s, which is definitely not enough for a door sensor. The same
   standard then says that such errors should be propagated to bit 0 in the
   "instanceErrorByte", which python-dali does not query. However, my
   devices unfortunately also propagate this status into the
   "inputDeviceError", and that means that the initial discovery of
   instance numbers to instance types won't recognize these buttons at
   all.
   
   I was not able to find a reference in the standard whether any
   "instanceError" propagates to the "inputDeviceError", but even if this
   was an incorrect behavior, these devices exist, one can buy them, and
   presumably using them as a kind-of persistent contact inputs still makes
   sense; just to provide some data, I have:
   
   - magnet and a reed switch for door status monitoring,
   - a "permanent" switch for disabling automation at a hallway where our
     baby sometimes sleeps.
   
   I think that both use cases make sense, and I would prefer python-dali
   to not skip over some input devices which actually work just fine.
   
   Fixes: 0cfddb7 Add support for DALI 24-bit event messages
