use official unit of measure for Lux in wiffi component
Add a mapping for the wiffi unit of illuminance 'lux' to the Home Assistant unit 'lx'. This fixed the following warning during startup:
```
2023-02-04 10:28:30.653 WARNING (MainThread) [homeassistant.components.sensor] Entity sensor.helligkeit (<class 'homeassistant.components.wiffi.sensor.NumberEntity'>) is using native unit of measurement 'lux' which is not a valid unit for the device class ('illuminance') it is using; expected one of ['lx']; Please update your configuration if your entity is manually configured, otherwise create a bug report at https://github.com/home-assistant/core/issues?q=is%3Aopen+is%3Aissue+label%3A%22integration%3A+wiffi%22
```
* add support for state_class measurements in wiffi integration
* use new STATE_CLASS_TOTAL_INCREASING for metered entities
like
- amount of rainfall per hour/day
- rainfall hours per day
- sunshine hours per day
* Update homeassistant/components/wiffi/sensor.py

* add config option to set timeout for wiffi devices
Wiffi devices allow to configure the update period (=
full_loop_minutes). The integration shall respect the configured update
period and therefore need a configuration for the timeout, too.
* Move timeout from config flow to option flow
* add test for option flow
* Add integration for wiffi devices
wiffi devices are DIY board manufactured by stall.biz.
Several devices are available, e.g. a weather station (weatherman), an
indoor environmental sensor (wiffi-wz) and some more.
This intgration has been developed using a weatherman device, but should
also work for other devices from stall.biz.
* Fix pylint warning
* Use WIFFI / STALL WIFFI instead of wiffi to be consistent with stall.biz
* Don't update disabled entities.
