sensor: max30101: Add heart rate sensor driver

Adds basic sensor driver support for the Maxim MAX30101 heart rate
sensor.

This driver does not yet support any sensor triggers such as the data
ready trigger, or runtime changing of sensor attributes.

Default configuration values were taken from the MikroE Hexiwear driver.
