Softmask always returns multichannel output #21

norbert.softmask allows to compute the ratio mask for mono mixtures without giving a channel axis. Why, in this case, is the channel axis required for the mixture?

I would propose to not allow to omit the channel axis at all. This makes things easier to handle.
