 *********************************************************************************************
 * Optionally allowing users to tweak calibration registers:
 * - In addition to possible rules add a rule containing the calib.dat string like:
 *   - rule3 on file#calib.dat do {"angles":{"angle0":180,"angle1":176}} endon
 *   - rule3 on file#calib.dat do {"rms":{"current_a":4194303,"current_b":4194303,"voltage":1613194},"angles":{"angle0":200,"angle1":200},"powers":{"totactive":{"a":2723574,"b":2723574},"apparent":{"a":2723574,"b":2723574},"reactive":{"a":2723574,"b":2723574}}} endon
 * - Restart Tasmota and obeserve that the results seem calibrated as Tasmota now uses the information from calib.dat
 * To restore standard calibration using commands like VoltSet remove above entry from rule3
