Window openings : send the raw value instead of large roundings

[lpaso]

Hi,

First of all, thank you for your great plugin, it's the main one I use on Homebridge and it's a "life saver" :)

But concerning the window openings, only having 0, 20, 40, 60, 80 and 100% opening states is a too restrictive.

As Homekit can set the opening percentage from 0 to 100 by increment of 1, instead of having multiples URL to manage the opening, could you (maybe optional) with a single URL where the value is passed from homekit ? As a result, setting the opening in Homekit to 52% open could set the real opening to 52% instead of 60%.

Also, the "open_url" seems to be in fact the "close" status of Homekit and the "close_url" seems to be in fact the "open" status of Homekit ;)

Thank you very much.
