Fix for #417

I added a check to the method `busylight.lights.light.Light.update`
that prepends a zero byte to the bytes object that will be sent to
a device if the current platform is Windows. This is necessary because
the Windows HID API requires a report ID to be sent with the data and
the underlying hidapi library doesn't seem to handle this for us on Windows
but does handle it on Linux and macOS.
