co⚡e: Sparkplug™ MQTT edge

Added support for obtaining certificates with no Country or Organization [#106]

v1.3.1.1
Patch of NBIRTH bug and Log bug

1.3.1.0

Implementation of trigger for a DDEATH message as input FB_Device
Implementation of Device unplugging "on the fly" causes an exception
Implementation of FB_EoNTopicProvider & FB_DeviceTopicProvider Which helps to significantly lower the WCONCAT function usage count as string manipulation is known to be CPU consumption prone.

V1.3.0.2 implemented DDEATH [#101]

Merged branch i-campbell into trunk ( completion of FB_Paylaod [#11] )

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

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

[#89] Implemented Node Commands

[#11] Added 8 encode objects to Payload

[#11] completed 12 boxes of decode Payload
Also fixed bug with MetaData STRUCT, where size and seq were WSTRINGs, now ULINTs

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)

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

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

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
