Change default V5 to mbus

Browse Source 
At least the BE and the NL DSMR devices use MBUS.
Therefor we make the MBUS obis reference generic, and convert the V5
telegram to use MBUS values.

Also remove BELGIUM_MAX_POWER_PER_PHASE as this was a duplicate.

Finally set self.maxDiff = None to have a full test output on some
tests.
