evaluate integration with sbfspot project

[keerekeerweere]

A lot of code and functionality is shared with the sbfspot project. This project targets windows and linux deployments on more powerfull devices such as raspberry pi's, vm's, etc. . However reading the bluetooth data from the inverters is very similar except that the esp32 does not require the sma netconnect functionality.
A first attempt was made, to fork the sbfspot project but was not feasible in a reasonable amount of time for a single developer.
e.g. next to the win32 and linux targets, an embedded or esp32 platform target could be added and try to maximise code sharing, either directly through cpp files or through subclasses of the existing classes in sbfspot.
