NeoPool add data validation and statistics

[curzon01]

Description:

Adds NeoPool data validation for some sensors and communication statistics (default enabled for ESP32, default disabled for ESP8266, to enable it on ESP8266 define NEOPOOL_RANGE_CHECKS and NEOPOOL_CONNSTAT).

Data validation

The following controller measurements are checked against a min/max range, values outside the range are discarded:

• Ionization level [0..100] (%)
• Hydrolysis intensity level [0..x] (% or g/h), x is system-dependent
• pH level [0..14]
• Redox level [0..1000] (mV)
• Chlorine level [0..10.0] (ppm)
• Conductivity level [0..100] (%)
• Temperature sensor [0..65] (°C)

Communication statistics

add the following stats to NeoPool SENSOR topic

    "Connection": {
      "Time": "2024-07-03T15:00:00",
      "MBRequests": 36103,
      "MBNoError": 34888,
      "MBIllegalFunc": 0,
      "MBIllegalDataAddr": 0,
      "MBIllegalDataValue": 0,
      "MBSlaveError": 0,
      "MBAck": 0,

    }

• MBRequests is the total number of system request
• MBNoError is the total number of system responses without error
• MBNoResponse is the number of MBRequests having no repsonse
• DataOutOfRange is the total number of values outside the valid range
• All other MB... items are Modbus response errors (Modbus error 1..14)
