Add CO2V1_WiFi_Smart_CO2_detector (#3951)

* Add CO2V1_WiFi_Smart_CO2_detector

Almost the same as inkbird_pth9cw_airquality, but had to add proper scaling.
Device: WiFi Smart CO2 detector
CO2V1
Cheap Aliexpress chinese sensor.
Description: Tuya Wi_Fi Smart Co2 Meter Box Accurate Real Time Indoor Smoke Alarm Detector

* feat (co2v1_co2_sensor): rename from detector to sensor

- avoid redundant words in naming.
- since this gives readings rather than an alarm or binary sensor, it is more a sensor or monitor than detector
- use only lower case in filenames to avoid case sensitive vs insensitive filesystem issues.
