Merge #36

36: Add stm32f0 hid mouse example for RTIC v1.0 r=AfoHT a=barafael

This example was ported from rtic_v0.5/stm32f0_hid_mouse/. It compiles and runs on stm32f072 nucleo. RTT and GPIOs work. Not sure if USB I/O and actual mouse function work - hence draft PR. I'd be glad if somebody could help me test this.
