Currently, ImageBinarization doesn't support transparent colors (e.g., RGBA) so I open this issue to see your opinions:

leave it unsupported
drop the transparent channel
keep the transparent channel and output the transparent gray color, e.g., GrayA{T} (Unfortunately, T can't be Bool here).

I'm not sure if we should support this. Neither dropping or making output GrayA{Float64} type doesn't sound very good to me.
