Raw data extraction from Debug

[lettore]

Hi, first of all thank you for this project, you saved my life.
That said I managed to connect Home Assistant via TCP with Node Red using the debug data over MQTT.
I want to share my considerations:

1. it's possible to add a topic RAW to send the original data coming from Rflink serial bus without any modifications?
2. actually the debug topic receive 2 message for every single message incoming, one with DATA and another with JSON, it's possible to publish this to two separates topics rflink/debug/data and rflink/debug/json?
3. the debug topic is retained, this can be useful for debugging but if you use it as I'm doing at every reconnection to the server I get the last published topic, and it's not what should happen. You can make this an option?
   If you can just publish the raw data on a separate topic all the rest can remain the same.
   Thank you
