[Fan] Change Rotation Speed from percentage to levels

[vadimpronin]

This PR changes units for Rotation Speed of a Fan from % to speed levels.
Sonoff fans have only 3 speed settings presented as Roman numerals on the remote (I, II, III).
Original implementation presented these levels as 33%, 66% and 99% in HAP.
Changing them to 1, 2 and 3 seems more intuitive and inline with original sonoff design

Oh wow I did not even know this scale/functionality was available in HAP. Might look into changing my other plugins too!

Out of interest, if you are using the existing version of the plugin with % scales, then change git branch to your changes, does the scale automatically update in the home app? or does it require removing the accessory for it to be re-added with the new scales?

This is really cool, thank you

@vadimpronin I was hoping you could check something further for me. (I do not have an iFan myself)

• Update to the ewelink plugin beta which includes your fan changes
• Update to the beta version of the Homebridge UI - I have hopefully made some changes to support the fan scale changes within the UI itself - on the Accessories page

Would you be able to confirm that it works in the Homebridge UI? ie - not displaying a % and also it sliding properly between 0 - 1 - 2 - 3?

Hey @bwp91

does the scale automatically update in the home app? or does it require removing the accessory for it to be re-added with the new scales?

The scale updates automatically after a few minutes

Would you be able to confirm that it works in the Homebridge UI? ie - not displaying a % and also it sliding properly between 0 - 1 - 2 - 3?

Being able to change the scale in the UI is cool!
Will check it tomorrow!
