v1.5.0 to improve frequency precision

### Releases v1.5.0

1. Improve frequency precision by using float instead of ulong, Check PR [change variable period from unsigned long to float #7](#7)
2. Remove compiler warnings
3. Update `Packages' Patches`
4. Add `strict` option for PIO `lib_compat_mode`
5. Split `changelog.log` from `README.md`

 sentence=This library enables you to use Interrupt from Hardware Timers on SAMD-based boards such as SAMD21 Nano-33-IoT, Adafruit SAMD51 Itsy-Bitsy M4, SeeedStudio XIAO, Sparkfun SAMD51_MICROMOD, etc.
 paragraph=These SAMD Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's mandatory if you need to measure some data requiring better accuracy. It now supports 16 ISR-based Timers, while consuming only 1 Hardware Timer. Timers interval is very long (ulong millisecs). The most important feature is they're ISR-based Timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks.
