Slider to adjust speed for Robot Cleaner
Hello. First, thank you very much for this wonderful plugin, it works perfectly with my Dream D9!

Do you think it would be possible to implement a slider instead of different switches, in order to control the Suction Mode? I know that another plugin [https://github.com/homebridge-xiaomi-roborock-vacuum/homebridge-xiaomi-roborock-vacuum/blob/HEAD/models/speedmodes.js](url) can do that. For example: OFF /  0-25% = Quiet / 25-50% = Normal / 50-75% = Strong / 75-100% = Turbo.

Obviously, it should be an option only, because people could prefer the switches.

EDIT: event better, is it possible to have steps in the slider?
