Ricoh Theta V: 60 pictures HDR

This script captures 60 (!) pictures with different exposure times.

/**
 * HDR capturing example (Ricoh Theta V).
 * Author: Camera Controller
 * Web: http://www.tequnique.com/cameracontroller
 * Description: This example shows how to capture exposure series (e.g. for HDR) using 60
 *              different exposure times.
