// There are two ways to utilize the dynamic sensor module:
//   1. Use as an extension in an existing hal: declare dependency on libdynamic_sensor_ext shared
//      library in existing sensor hal.
//   2. Use as a standalone sensor HAL and configure multihal to combine it with sensor hal that
//      hosts other sensors: add dependency on sensors.dynamic_sensor_hal in device level makefile and
//      write multihal configuration file accordingly.
//
// Please take only one of these two options to avoid conflict over hardware resource.
//
//
// Option 1: sensor extension module
