co⚡e: Sparkplug™ MQTT edge

Library v1.1.1.5

Refactored both EoN and Device with an internal FB_StateMachine in SFC

Working:
EoN -> Birth, Publish, Rebirth.

Needs polish:
Device(s) -> Birth, Publish, Rebirth.
Several issues in device allready located, but not yet fixed (work in progress)

Version 1.1.1.0
merged hermsen branch 1.1.0.14 into trunk
Fixed the Rebirth publish issue for a connected device after the Server Node requests an EoN Rebirth
Fixed improved readability and control over the state entry, exit and continuous parts in EoN/Device
Fixed stable Device state

Device V1.1.0.1

TODO
* Check publishing DBIRTH Topic SeqNum (should be working)
* Check publish DDATA SeqNum (triggers REBIRTH, not correct yet)
* Publish DDEATH of a Device when occurs

Optimisations
Various methods of the EoN are rewritten into standalone Functions as devices and EoN share these (following DRY principle)

FB_Device with corresponding binding methods,
Added Device binding code into FB_Edge_Of_Network_Node,
ISparkplugDevice (device binding Interface),
