Extending DL models to 3D data

[ziatdinovmax]

The semantic segmentation models need to be extended to work with 3D data. This should be very straightforward - just introduce an option to select between 1D, 2D, and 3D cases to ConvBlock, UpsampleBlock, etc.

@aghosh92 Is this something you'd be interested in?

Yes. I'll be interested in these. Thank you.
I'll send you updates on these tasks sometime.

I have added 3D support to the individual nn blocks but not to the fcnns. I was wondering what's the best way to do it. Can I also be assigned to this issue?
