Switch to a push model instead of polling

[tronikos]

• Switch to a push model, similar to Tuya, which is more efficient than polling.
• Moved all configuration to yaml, similar to Tuya. Any future additional sensors will only require yaml changes which simplifies the process even more.
• Sensors that get raw values (air handler CFM and RPM) use on_datapoint_update trigger similar to Tuya, see https://esphome.io/components/tuya#on-datapoint-update
• On reboot, until the device receives data, HA should now get unknown for all the entities instead of 0 that was getting before which could unintentionally trigger automations.
