RNode and Meshtastic cannot interact.

I did ask in the Reticulum Discord if it was possible to run Reticulum over Meshtastic by using the serial transport in Reticulum connected to the serial module in Meshtastic. It is technically possible but inefficient. The person who answered my question said you'd need to use Meshtastic in ShortFast mode to make it even remotely practical.

Essentially it was using the serial transport connected to a Meshtastic node in place of the RNode thus allowing the Meshtastic device to perform the role of both.

[Reticulum] --Serial Transport---> Meshtastic Node's UART1 ---> Meshtastic Serial Module --->Meshtastic LoRa  ---> Remote Meshtastic Node's Serial Channel --> Remote Meshtastic Nodes UART1 --> [Remote Reticulum Client]

They also pointed me to a Github project of theirs that basically did just that, but I cannot for the life of me find it to link it.
