v1.1.0 for new `PWM_manual` example, etc.

### Releases v1.1.0

1. Add example [PWM_manual](https://github.com/khoih-prog/ESP32_FastPWM/tree/main/examples/PWM_manual) to demo how to correctly use PWM to generate waveform. Check [About DCValue in setPWM_manual #2](khoih-prog/AVR_PWM#2)
2. Add function `setPWM_DCPercentage_manual()` to facilitate the setting PWM DC manually by using `DCPercentage`, instead of `absolute DCValue` depending on varying resolution
3. Fix glitch when changing PWM frequency. Check [Frequency change on cycle end. #1](#1)
