Mesh TensorMaps: Start with bounding box

[lucidtronix]

This is great @paolodi ! I think there may be an even simpler minimum viable product here though. What if we simply argmax and argmin the SAX segmentations in the left ventricle and myocardium channels (axes 1 and 2). Separate TMAPs for each. I think it makes sense for meshes to add their own INTERPRETATION enum as new evaluations, losses, and visualizations are going to be needed. So the shape would be (6,) and channel Map would be {min_x: 0, ..., max_x: 3, ..., max_z: 5}. Obviously, this approach is forced to be axis aligned in the SAX voxel space which your proposal solves if I'm reading it right. If you're already underway with your better approach, I'm happy to tackle this the stupid way and you can review. What do you think?

Absolutely, @lucidtronix, I like your proposal! And if you have something clear in mind, please go ahead and I'll be happy to review it. You're right, I guess I was referring to a bounding box that would maintain some information about the actual 3-D orientation of the object and rely less on the orientation and alignment of the SAX view, which is chosen by an operator. Clearly the mismatch between the two approaches is significant only if the view is not well aligned (i.e., in a very misaligned view, you would require a 'bigger than necessary' bounding box to enclose the object if you just take min and max). But we could fix for that later on!

Sorry I was playing with the project table and I understood what shifting to 'Done' does :-)
