v2.1.0 for new PWM_manual example, to add function setPWM_DCPercentage_manual() to facilitate the setting PWM DC manually and to optimize for PWM speed when changing `dutycycle` while using same `frequency`

Releases v2.1.0

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
3. Optimize for PWM speed when changing dutycycle while using same frequency

v2.0.3 to add example `PWM_StepperControl` to demo how to control Stepper Motor using PWM

Releases v2.0.3

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

v2.0.2 to convert to `h-only` code and to optimize library code, etc.

Releases v2.0.2

1. Convert to h-only code
2. Optimize library code by using reference-passing instead of value-passing
3. Add example multiFileProject to demo for multiple-file project
4. Update Packages_Patches and test with new ArduinoCore-mbed mbed_portenta core v2.7.2

v2.0.1 to fix PWM_Multi example by not using HRTIM pinD3 and pinD6 at the same time and temporary fix polarity for HRTIM PWM pins

Releases v2.0.1

1. Fix PWM_Multi example by not using HRTIM pinD3 and pinD6 at the same time
2. Temporary fix polarity for HRTIM PWM for core v2.6.1-. Check Portenta: PWM on HRTIM has inverted corner case values #352. To be modified when the issue is fixed.

v2.0.0 with completely new code to fix no PWM output issue and to permit start, stop, change and restore the settings of any PWM channel on-the-fly

Releases v2.0.0

1. Completely new code to fix no PWM output issue. Check No PWM-Output signals #1
2. To permit start, stop, change and restore the settings of any PWM channel on-the-fly
