TreatLife DS03 RotationSpeed is not a number

Describe the bug

This doesn't appear to be causing any functional issues, but it's worth noting, and maybe worth fixing if it could potentially cause problems in the future.

I have a couple of TreatLife DS03 combo switches. Currently testing this FanLight config:

{
            "type": "FanLight",
            "name": "Ceiling Fan",
            "id": "<redacted>",
            "key": "<redacted, but what a pain in the butt it is to acquire these!>",
            "manufacturer": "TreatLife",
            "model": "Ceiling Fan Dimmer Switch DS03",
            "dpLight": 9,
            "dpBrightness": 10,
            "useBrightness": true,
            "minBrightness": 100,
            "scaleBrightness": 1000,
            "dpActive": 1,
            "dpRotationSpeed": 2,
            "maxSpeed": 4
}

For some reason the switches (these are firmware v3.3) send the fan speed as text instead of a number. I have confirmed this with tuya-cli. The response looks like this:

{
  '1': true,
  '3': '4',         <---- fan speed is sent as a text string ¯\_( ͠° ͟ʖ ͠°)_/¯
  '9': true,
  '10': 1000,
  '105': 100,
  '106': 'mode1',
  '108': 1
}

This causes an error in the log, since the plugin obviously expects a number instead of text:

Sorry, same as #461

Actually, I just noticed that when I define dpActive and dpRotationSpeed, fan speed does not appear properly in HomeKit; it's always 0%. If I eliminate those settings and only define maxSpeed, the fan controls work properly.

Still having issues getting the dimmer control working properly, but that's a different issue.
