Those tablets don't need special initialization, but are reporting
the events with the wrong usages:
- tip switch is used when the eraser should be used
- eraser is used instead of the secondary barrel switch

Add tests for those so we don't regress in the future.

Currently we set x/y tilt to 0 to not trigger the bpf program
compensate_coordinates_by_tilt()
