Version 2.3.0

Suitable for CVE add-on hardware revision 2 and non-CVE add-on revision 1. The first revision of the add-on based on the ESP8266 is not supported due to memory limitations.

!Upgrading to this version will format the flash drive and reset all settings (incl. wifi)!

Device Support:
feat: Add DemandFlow/QualityFlow, HRU eco/350, AutoTemp and HeatPump (WPU) settings and status labels
feat: rewritten i2c for HW rev 2, added itho query commands to debug page.
feat: add possibility to change settings of itho CVE units, use on your own risk
feat: move add-on settings to menu system settings

API:
feat: make API sensor update frequency configurable
feat: Add virtual remote buttons to API
feat: Add last command, command origin + timestamp to API

Remote support:
feat: Include support for RFT-RV and RFT-CO2 remotes (full join handshake not possible yet)
feat: Add remote hum/temp/co2/battery to api
feat: First try at calibration method for CC1101 modules (not fully functional yet)
feat: Improved RF message handling and decoding

Status info:
feat: Added possibility to readout status of internal device status
feat: Decode 31D9 message
feat: Decode 31DA message
feat: Itho internal device status available through web page and API
fix:  witch to percentages for HA Discovery support #31

Stability:
feat: Improve I2C reliability
feat: Mutex i2c tasks
feat: change init check to not rely on attiny init anymore
feat: move to LittleFS as filesystem

Settings:
feat: make hostname configurable
fix:  provide don't save config checkbox before reboot (otherwise changes using the file system editor were overwritten on reboot)
fix:  status page could keep updating even if page was left
fix:  Bugfix in MQTT password config code
