feat: properly implement continuous mode (fifo)
ddcb8a3 
the previous code was matching Arduino_LSM9DS1 a bit too closely,
not taking into account thet the FIFO must be read from different
registers in BMI270.

feat: make library compatible with Nano 33 BLE Sense rev2
269c80a 
* Needs arduino-libraries/Arduino_BMI270_BMM150#56 to properly handle BMI270 in FIFO mode
* The user should define NANO33_BLE_REV2 as early as possible to include the proper libraries (fixed the examples)
* `while (IMU.accelerationAvailable())` replaced with `if (IMU.accelerationAvailable())`, shouldn't change anything in existing code since Arduino_LSM9DS1 was always returing only one sample
