v1.2.0 to optimize speed with new `setPWM_DCPercentageInt_manual` function to improve speed almost 50% compared to `setPWM_DCPercentage_manual` of previous `v1.1.0`, to add example `PWM_SpeedTest`, etc.

Releases v1.2.0

1. Optimize speed with new setPWM_DCPercentageInt_manual function to improve speed almost 50% compared to setPWM_DCPercentage_manual of previous v1.1.0
2. Add example PWM_SpeedTest to demo the better speed of new setPWM_DCPercentageInt_manual function
3. Improve README.md so that links can be used in other sites, such as PIO

v1.1.0 for new PWM_manual example, to add function setPWM_DCPercentage_manual() to facilitate the setting PWM DC manually, etc.

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 PWMPeriod
3. Catch low frequency error and use lowest permissible frequency

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 AVR ATtiny-based boards (ATtiny3217, etc.), using megaTinyCore

Initial Releases v1.0.0

1. Initial coding to support Arduino AVR ATtiny-based boards (ATtiny3217, etc.) using megaTinyCore
