co⚡e: Sparkplug™ MQTT edge

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

[#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)

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

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

v0.9.9.5
Exponential Backoff Timer Implemented

0.9.1.2
MANY MANY Changes !-)

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

v0.9.0.3
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

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,

TLS Support for EoN
PublishPeriod
Correction of illegal Characters (/,#,+) in device, node and groupid
Many fixes etc.
