 * @brief Initializes the secure psuedo-random generator
 * @param sampling_mode Sampling mode to use for finding an entropic bit. See @b sampling_mode.
 * @return [bool] True if init succeeded, False otherwise
 * @note Sampling mode controls the speed (and accuracy) of the source-selection algorithm.
 * Setting SAMPLING\_THOROUGH retrieves 1024 samples per bit polled and takes ~4 seconds to run.
 * Setting SAMPLING\_FAST retrieves 512 samples per bit polled and takes ~2 seconds to run.
 * @note Using the faster sampling mode may result in a less-entropic source byte being selected due to less
 * samples being collected. It is recommended to use THOROUGH.
