v1.7.0 to add support to nRF52 core v0.22.0+

### Releases v1.7.0

1. Add support to Adafruit nRF52 core v0.22.0+
2. Add support to nRF52 Raytac MDBT50Q_RX Dongle

**Warnings for Releases v1.6.0-** : Use [`Adafruit nRF52 v0.22.0+`](https://github.com/adafruit/Adafruit_nRF52_Arduino/releases/tag/0.22.0) will create **compiler errors**.

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. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's necessary if you need to measure some data requiring better accuracy",
