Implemented parsing of advanced diagnosis menu contents

[tspopp]

See issue #17.

This PR fixes:

• MITM Mode: Errors were previously not transferred to HMI ⚠️
• MITM Mode: Race-Condition which leads to dropped bytes in the main channel connection

This PR adds:

• Process error messages (message id 74)
• Forward error messages in MITM mode
• Publish error message content to MQTT
• Changed and customizable MQTT publish behavior (fixes MQTT - publishing frequency  #19)
• Possibility to debug and publish raw heat pump messages received on each channel
• New MQTT topics for main message:

Value	MQTT Topic	Format	Unit	Other Information
Present Error Code	$root/main/errorCode	uint8		0 if there is no present error, else the error-code
Fan Speed	$root/main/fanSpeed	uint16	rpm	Removed since the message contained the pwm level and no rpm value.
Fan-Level PWM	$root/main/fanPWM	float	%
State: PV Input Signal Detected	$root/main/statePV	bool
Setting: 1st Fan-Level PWM	$root/main/settingPWM_1	uint8	%
Setting: 2nd Fan-Level PWM	$root/main/settingPWM_2	uint8	%
Setting: 3rd Fan-Level PWM	$root/main/settingPWM_3	uint8	%
Setting: Min. Target Temp	$root/main/settingMinTargetTemp	uint8	°C
Setting: Min. Anti-Legionella Temp	$root/main/settingMinLegionellaTemp	uint8	°C
Setting: Wattage Heat Element	$root/main/settingWattageElement	uint16	W
Setting: Boiler Capacity	$root/main/settingBoilerCapacity	uint16	l
Setting: Boiler Brand	$root/main/settingBoilerBrand	Enum		Atlantic, Thermor, Sauter, No Name
Capability: Has Heat Exchanger	$root/main/capabilityHeatExchanger	bool

Raw Message (Debug Mode Only)	$root/main/debug	string

• New MQTT Topics for HMI message:

Value	MQTT Topic	Format	Unit	Other Information
PV Input Activated	$root/hmi/pvInputActivated	bool
Raw Message (Debug Mode Only)	$root/hmi/debug	string

• New MQTT Topics for error messages:

Value	MQTT Topic	Format	Unit	Other Information
Error Number	$root/error/%requestId/errorNumber	uint8
Error Code	$root/error/%requestId/errorCode	uint8
Date	$root/error/%requestId/date	string		e.g. 25.5.2024
Time (hh:ss)	$root/error/%requestId/time	string		e.g. 21:29
Water Temperature	$root/error/%requestId/waterTemp	float
Lower Evaporator Air Temperature	$root/error/%requestId/evaporatorAirTempLower	float
Upper Evaporator Air Temperature	$root/error/%requestId/evaporatorAirTemp	float
Fan-Level PWM	$root/error/%requestId/fanPWM	uint8	%
Total Heatpump Hours	$root/error/%requestId/totalHeatpumpHours	uint16
