Nicera D3-323-AA is a PIR sensor for human detection. It has support for raw data measurements and detection notification. The communication protocol is custom made and therefore needs to be GPIO bit banged. The device has two main settings that can be configured: a threshold value for detection and a band-pass filter. The configurable parameters for the band-pass filter are the high-pass and low-pass cutoff frequencies and its peak gain. Map these settings to the corresponding parameters in the `iio` framework. Raw data measurements can be obtained from the device. However, since we rely on bit banging, it will be rather cumbersome with buffer support. The main reason being that the data protocol has strict timing requirements (it's serial like UART), and it's mainly used during debugging since in real-world applications only the event notification is of importance. Therefore, only add support for events (for now).
