Add basic support for aerox 9 buttons

[zebreus]

This PR adds support for configuring the buttons on the Aerox 9 wireless (and probably wired).

I am not sure if I am missing something or if the Aerox 9 is the only device that has a button configuration split among multiple commands ([0x2a, 0x00], [0x2a, 0x01], [0x2a, 0x02]). I didn't find a way to bundle all three in one command without modifying mouse.py, so there are now three flags for configuring the buttons (--buttons1, --buttons2, --buttons3), which is pretty clunky. Ideally, we can merge them into one --buttons flag that sends multiple commands to the mouse. What would be the best way to go about that?

closes #239

This PR now also enables sending multiple packages with one CLI command to have a single --buttons command for the Aerox 9. I implemented this by allowing process_value to return a list of packets if there are multiple. setting_info for the buttons commands now supports a split_packet_at field to specify where a packet should get split.

There are some other devices that have a second packet to configure wheels bindings, but the A9/WA9 are the only ones to have button bindings spliced in multiple packets. But they are the only SS mice with that much buttons. :)
