v1.4.0 to fix multiple-definitions linker error
### Releases v1.4.0 1. Fix `multiple-definitions` linker error. Drop `src_cpp` and `src_h` directories 2. Add example [multiFileProject](examples/multiFileProject) to demo for multiple-file project. 3. Fix `reattachInterrupt()` bug. Check [bugfix: reattachInterrupt() pass wrong frequency value to setFrequency() #19](khoih-prog/ESP8266TimerInterrupt#19) 4. Add support to Adafruit `NRF52840_LED_GLASSES` 5. Optimize library code by using `reference-passing` instead of `value-passing` 6. Update all examples 7. Update `Packages_Patches`

The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
1212
Therefore, their executions are not blocked by bad-behaving functions / tasks.
1313
This important feature is absolutely necessary for mission-critical tasks.
