Fixes DiceCELoss for multichannel targets. Currently if "target" (ground truth label) is provided as a multichannel data (each channel is binary or float), then current DiceCELoss attempts to convert it to 1-channel using argmax (which could be impossible with overlapping labels). There is no need for argmax, since pytorch's cross entropy can handle multi-channel targets already. ### Types of changes <!--- Put an `x` in all the boxes that apply, and remove the not applicable items --> - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [ ] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. - [ ] Documentation updated, tested `make html` command in the `docs/` folder.

Fixes DiceCELoss for multichannel targets.
Currently if "target" (ground truth label) is provided as a multichannel data (each channel is binary or float), then current DiceCELoss attempts to convert it to 1-channel using argmax (which could be impossible with overlapping labels). There is no need for argmax, since pytorch's cross entropy can handle multi-channel targets already.
