JsonConverterWithSchemaEvolution does not support subtopic

[ilcorvo]

Hi,
we are using JsonConverterWithSchemaEvolution.
It is a great converter because it automatically solves issues related to malformed data sources (null values or float with no decimal digits).
The issue is that i does not support subtopics in the mqtt source address:

• "machineNamePLCNameSensorName" works
• "machineName/PLCName/SensorName" does not work

JsonSimpleConverter supports subtopics.
Thanks for support.
