Add "water tank attached" and "mop attached" sensors based on existing, available attributes

[chriswood1001]

Is your feature request related to a problem? Please describe.

I create automations related to the state of both the water tank and the mop attached states. For example, if the mop has been attached for 3 runs then I send a phone notification to replace the mop, reset automatically once the "mop attached" state turns off. Or if the water tank is detached (forgotten by the sink) then I send a phone notification to refill and replace it.

Describe the solution you'd like

Extract the existing vacuum attributes into independent binary sensors.

• Existing vaccum attribute "waterBoxStatus" maps to whether the water tank is attached. 1: Attached. 0: Removed
• Existing vacuum attribute "waterBoxCarriageStatus" maps to whether the mop is attached. 1: Attached. 0: Removed

Describe alternatives you've considered

I've created my own binary_sensor templates based on the vacuum attributes. Ideally they'd be natively exposed attributes since the data is already there.

Vacuum

Attributes are confirmed to reflect water tank and mop attached states for:

• S7+[roborock.vacuum.a15]
• S8+[roborock.vacuum.a51]

waterBoxStatus attributes goes from 1 to 0 when water tank is removed

waterBoxCarriageStatus attributes goes from 1 to 0 when mop mount is removed mopForbiddenEnable attributes goes from 1 to 0 when mop mount is removed

When removing dusk bin out of the Roborock there is no attribute change from 1 to 0

waterBoxCarriageStatus doesn't change at all it is 1 all the time - S6 MaxV
