Description

EnsureChannelFirst should be used in place of AddChannel, however it requires that metadata be provided as MetaTensor inputs or separate dictionaries. This doesn't substitute for AddChannel which required neither of these things and so can't be used in the situation where one has data known to have no channel dimension nor metadata and we just want to hard-code adding a 1-sized channel dimension. This is useful in a lot of examples that use generated data and not loaded files that come with metadata, and avoids forcing the user to use MetaTensor.
