Whicht typ of data Stream to use with zeRGBa?

Interestingly, in the iOS app you can’t even choose a datastream with a String data type when the zeRGBa widget is set top “Merge” (which according to the documentation should be called “Advanced mode”).

@Eugene @BlynkAndroidDev it looks like the zeRGBa widget needs some work, assuming that it’s going to be retained going forward.
