v1.2.2 to add support to Seeeduino nRF52840-based boards, such as XIAO_NRF52840 and XIAO_NRF52840_SENSE* etc. using Seeeduino `mbed` 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 mbed core
2. Add astyle using allman style. Restyle the library

v1.2.1 to fix `DutyCycle` and `New Period` display bugs.

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. Update examples

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

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 MBED nRF52-based boards (Nano_33_BLE, Nano_33_BLE_Sense, etc), using ArduinoCore-mbed mbed_nano or old mbed (v1.3.2-) core

Initial Releases v1.0.0

1. Initial coding to support Nano-33-BLE or Nano-33-BLE_Sense boards using

• Arduino mbed_nano core 2.5.2+ for NRF52-based board using mbed_nano core such as Nano-33-BLE if you don't use NRF_TIMER_1.
• Arduino mbed core v1.3.2- for NRF52-based board using mbed-RTOS such as Nano-33-BLE if you'd like to use NRF_TIMER_1.

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.
