co⚡e: Sparkplug™ MQTT edge

SparkPlugB v1.3.0.0 "Bonus"

Allows Multiple Devices to be connected to EoN
Multiple Device DBIRTH Publish without issue
Multiple Device DDATA Publish without issue

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)

v1.0.0.0
Deleted Embedded Resources
Updated some comments

v0.9.9.7 from branches/i-cambell/ to trunk

v0.9.9.5
Exponential Backoff Timer Implemented

v0.9.0.3
Revised EoN state machine
Improved MQTT Diagnosis feedback messages in sparkplug log (MQTTErrorToString)

Todo:
-Debug the EoN for a correct behaviour when connect-disconnect-connect (statemachine works but
the underlying code needs some more debugging as expected)
-Immutable startup logging (lib version etc) is currently static(!) and gets filtered by the verbosefilter

v0.0.0.31 from Aliazzz Branch

Fixed NDATA via ticket #63
1) Init Encoder in usual way,
2) ChangeDetection (adds data to internal encoder),
3) Block ChangeDetection and immediately Send Payload,
4) Repeat from step 1.

v0.0.0.30 solved [#57] / ERROR.PayloadNotEnoughMetrics
problem was bdseq wasn't part of AllMetrics
also corrected bdseq to ULINT / UInt64. was LINT/Int64

Updated trunk with Aliazzz Branch v0.0.0.29

V0.0.0.27 Fixed #58 EoN, NDATA: extra metric "seq" is not allowed
