Added backup register usage in 1.0.5, no examples yet but the functions are

Store max uint32[ 4 ] values to rtc ram rtc.setBackup(1, val_1); // save first value ... rtc.setBackup(4, val_1, val_2, val_3, val_4); // save 4 values
Restore max uint32[ 4 ] values from rtc ram rtc.getBackup(1, &val_1); // get first value ... rtc.getBackup(4, &val_1, &val_2, &val_3, &val_4); // get all 4 values
