v1.2.2 to add support to Seeeduino nRF52840-based boards, such as XIAO_NRF52840 and XIAO_NRF52840_SENSE, using Seeeduino `nRF52` core, to add astyle using `allman` style and to restyle the library

Releases v1.2.2

1. Add support to Seeeduino nRF52840-based boards such as Seeed_XIAO_NRF52840 and Seeed_XIAO_NRF52840_SENSE, etc. using Seeeduino nRF52 core
2. Add astyle using allman style. Restyle the library
3. Update all examples
4. Update Packages' Patches to add Seeeduino nRF52 core

v1.2.1 to fix `DutyCycle` and `New Period` display bugs, to add support to Sparkfun Pro nRF52840 Mini, etc.

Releases v1.2.1

1. Fix DutyCycle bug. Check float precisison of DutyCycle only sometimes working #3
2. Fix New Period display bug. Check random dropouts #4
3. Display informational warning only when _PWM_LOGLEVEL_ > 3
4. Add support to Sparkfun Pro nRF52840 Mini
5. Update examples
6. Update Packages' Patches

v1.2.0 to fix `multiple-definitions` linker error, improve accuracy, DutyCycle to be optionally updated at the end current PWM period instead of immediately, etc.

Releases v1.2.0

1. Fix multiple-definitions linker error. Drop src_cpp and src_h directories
2. Improve accuracy by using float, instead of uint32_t for dutycycle. Check Change Duty Cycle #1
3. DutyCycle to be optionally updated at the end current PWM period instead of immediately. Check DutyCycle to be updated at the end current PWM period #2
4. Optimize library code by using reference-passing instead of value-passing
5. Add example multiFileProject to demo for multiple-file project
6. Update examples accordingly
7. Update Packages_Patches

v1.1.0 to add functions to modify PWM settings on-the-fly

Releases v1.1.0

1. Add functions to modify PWM settings on-the-fly
2. Add example to demo how to modify PWM settings on-the-fly

v1.0.0 to support ISR-based multi-channel PWM for nRF52-based boards ( Adafruit Itsy-Bitsy nRF52840, Feather nRF52840 Express etc), using Adafruit_nRF52_Arduino core

Initial Releases v1.0.0

1. Initial coding to support nRF52-based boards, such as AdaFruit Itsy-Bitsy nRF52840, Feather nRF52840 Express, etc. using Adafruit nRF52 core

2. The hybrid ISR-based PWM channels can generate from very low (much less than 1Hz) to highest PWM frequencies up to 1000Hz with acceptable accuracy.
