Add STM32F103 port
Add a fully functional STM32F1 port, currently mostly targeting STM32F103 microcontrollers. This requires an 8 MHz XTAL. The maximum possible step rate is around 282K steps per second. This uses stm32flash to burn the firmware. The bootloader needs to be started by setting BOOT0 to 1 and resetting the MCU. There is no automatic bootloader, unlike on Arduino.

The LL UTILS driver contains a set of generic APIs that can be
|
||||
used by user:
|
||||
(+) Device electronic signature
|
||||
(+) Timing functions
|
||||
(+) PLL configuration functions
