Introduce the DATA_READY trigger and enable triggered buffering. Additional
changes include introduction of functions set_mode, drdy and get_triple,
allow either INT1/INT2 pin be used by specifying interrupt-names.
Triggered buffer was tested on both DATA_READY trigger and the hrtimer software
trigger.
