co⚡e: Sparkplug™ MQTT edge

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)

v1.1.0.0 Device Integration added into Trunk

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

Removed AliasMap and Metric, which were not used
Added units to the time parameters of FB_EoN

got rid of lib params, replaced with global variable

v1.0.0.0
EoN updated GetConnectionState to be private and exposed it as a classic output

v1.0.0.0
Deleted Embedded Resources
Updated some comments

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

v0.9.9.6 Fixed bugs in exponential reconnecting of FB_EoN Node
- it now issues a NBIRTH if it reconnects
- it now logs some better times for reconnecting
- it now is not as dependent on a 250ms cycle time for logging reconnect timers.

v0.9.9.5
Exponential Backoff Timer Implemented

0.9.1.4 fixed bug in log message for NCMD

Merging changes for unique client IDs
Reinstating fix to TLSHelpers

0.9.1.2
MANY MANY Changes !-)

Fixed bug with GetClientCert

v0.9.10.0

Fixed many tickets among "NCMD/Rebirth"
EoN now reacts to a Rebirth command from Ignition.
Fixed Payload decoder issue's,
fixed EoN "State machine" to react to Rebirth command

v0.9.0.6
Fixed the connect / disconnect (?) => TEST this ;-)
The EoN now gracefully disconnects after a MQTT CLIENT ERROR happens

0.9.0.4
Eon Enable moved to internal vars and initial value = TRUE
Added immutable log
Added project info for immutable log purpose
Added library info for immutable log purpose

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

recommit of v0.9.0.1:
EoN statemachine heavily revised
SparkplugB Log with verbose filter (none, err, err_wrn, err_wrn_inf)
EoN connect functionality

merging v0.0.0.35 library into trunk

v0.0.0.32 fixed find changes always initializing the encoder, which was resulting in seq counting up.

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

v0.0.0.28 fixes [#60] problem with ReencodeLengthDelimited

V0.0.0.27 Fixed #58 EoN, NDATA: extra metric "seq" is not allowed
Also fixed similar problem with DDATA
Snuck in a fix for array bounds in FB_SparkplugBSimple/FindChanges, which was producing 27 warnings
