Unhandled entry type 4 in read_devices

[flonou]

Hi,

When trying to create a backup in home-assistant it fails due to what seems to be a unmanaged AddrMgrUserType case in zigpy-znp.

The traceback is here :

Traceback (most recent call last):

ValueError: Unexpected entry type: 4

It seems like entry type 4 is Binding = 0x04

which is indeed not handled in read_devices
