Temperature monitor

Firmware for ESP32 to read and parse data from

• Two DS18B20 temperature sensors, this is boilerTemp variant
• One SI7051 temperature sensor, this is roomTemp variant

send this measurements with ESPNOW to the gateway, this should be low power since this hardware is powered from a battery.

TODO's and considerations

• Read measurements from DS18B20
• implement/merge compability with SI7051
• Implement ESPNOW for gateway communication
• Buffer measurements if ESPNOW messages are ignored
• optimize ESPNOW message building/memory allocation
• Add button functionality
• Sync destination MAC by BLE
• Remove debugging code
• improve/review timing/ system states
• improve low power performance
