v1.1.0 for new PWM_manual example, to add function setPWM_DCPercentage_manual() to facilitate the setting PWM DC manually, to fix glitch when changing PWM frequency

Releases v1.1.0

1. Add example PWM_manual to demo how to correctly use PWM to generate waveform. Check About DCValue in setPWM_manual #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

v1.0.1 to add example `PWM_StepperControl` to demo how to control Stepper Motor using PWM

Releases v1.0.1

1. Add example PWM_StepperControl to demo how to control Stepper Motor using PWM. Check Using PWM to step a stepper driver #16

v1.0.0 for hardware-PWM on ESP32-based boards, such as ESP32, ESP32_S2, ESP32_S3 and ESP32_C3, etc., using ESP32 cores

Releases v1.0.0

1. Initial coding for ESP32, ESP32_S2, ESP32_S3 and ESP32_C3 boards using ESP32 core
