Subject: [PATCH v3 1/5] iio: hid-sensors: Add proximity and attention IDs

The HID Usage Table at https://usb.org/sites/default/files/hut1_5.pdf
reserves:

- 0x4b2 for Human Proximity Range
Distance between a human and the computer. Default unit of
measure is meters;
https://www.usb.org/sites/default/files/hutrr39b_0.pdf

- 0x4bd for Human Attention Detected
Human-Presence sensors detect the presence of humans in the sensor’s
field-of-view using diverse and evolving technologies. Some presence
sensors are implemented with low resolution video cameras, which can
additionally track a subject’s attention (i.e. if the
user is ‘looking’ at the system with the integrated sensor).
A Human-Presence sensor, providing a Host with the user’s attention
state, allows the Host to optimize its behavior. For example, to
brighten/dim the system display, based on the user’s attention to the
system (potentially prolonging battery life). Default unit is
true/false;
