The previous commit improves num_strings parsing to not go over the maximum of 3 strings for WLED3 anymore. Likewise this default index for a hypothetical 4th string is invalid and could access registers that are not mapped to the desired purpose. Removing this value gets rid of undesired confusion and avoids the possibility of accessing registers at this offset even if the 4th array element is used by accident.
