There are three features used by various Logitech mice for
high-resolution scrolling: the fast scrolling bit in HID++ 1.0, and the
x2120 and x2121 features in HID++ 2.0 and above. This patch supports
all three, and uses the multiplier reported by the mouse for the HID++
2.0+ features.

The full list of product IDs of mice which support high-resolution
scrolling was provided by Logitech, but the patch was tested using the
following mice (over both Bluetooth and Unifying where applicable):

* HID++ 1.0: Anywhere MX, Performance MX
* x2120: M560
* x2121: MX Anywhere 2, MX Master 2S
