[miio] Add support for adjustable water output (THING_TYPE_VACUUM)

I have the new Roborock Vacuum S5 Max (s5e) which has an adjustable water output.

Analogous to the "fan power mode" the "water box mode" should be supported.

This means that in addition to fan_power the status channel should also contain water_box_mode: https://github.com/openhab/openhab2-addons/blob/50d850428573c3230c3835131868a5ad209e91bb/bundles/org.openhab.binding.miio/src/main/resources/ESH-INF/thing/vacuumThing.xml#L44 https://github.com/openhab/openhab2-addons/blob/50d850428573c3230c3835131868a5ad209e91bb/bundles/org.openhab.binding.miio/src/main/resources/ESH-INF/thing/vacuumThing.xml#L114-L118

The actions channel should also have the option water besides fan: https://github.com/openhab/openhab2-addons/blob/50d850428573c3230c3835131868a5ad209e91bb/bundles/org.openhab.binding.miio/src/main/resources/ESH-INF/thing/vacuumThing.xml#L32 https://github.com/openhab/openhab2-addons/blob/50d850428573c3230c3835131868a5ad209e91bb/bundles/org.openhab.binding.miio/src/main/resources/ESH-INF/thing/vacuumThing.xml#L196-L215

water_box_mode can take the following values: 200 - Off 201 - Low 202 - Medium 203 - High 204 - Customize (Auto)

The customize switch is only switched on if both fan_power and water_box_mode are set to the corresponding values (fan=106 & water=204).

Here only for information the response of the "get_status" command:
