v1.0.0 for STM32F/L/H/G/WB/MP1 PWM

### Initial Releases v1.0.0

1. Initial coding to support **STM32F/L/H/G/WB/MP1 boards** such as NUCLEO_H743ZI2, NUCLEO_L552ZE_Q, NUCLEO_F767ZI, BLUEPILL_F103CB, etc., using [`Arduino Core for STM32`](https://github.com/stm32duino/Arduino_Core_STM32)
2. The hardware-based PWM channels can generate very high PWM frequencies up with high accuracy.
