* Reimplement PGLab sensor to use a coordinator * fix spelling mistake on coordinator name * rename createDiscoverDeviceInfo function in snake_case * adding suffix pglab_ to PGLabBaseEntity/PGLabEntity constructor parameters * Fix docs of PGLabEntity::async_added_to_hass * make coordinator able to return the sensor native value * renaming PGLABConfigEntry in PGLabConfigEntry to be consistent with the integration naming * renamed entry function arguments to config_entry to be less confusing * pass config_entry to constructor of base class of PGLabSensorsCoordinator * set the return value type of get_sensor_value * store coordinator as regular instance attribute * Avoid to access directly entity from discovery module * Rearrange get_sensor_value return types
