DM-42685 Add a Tensor interface to analysis tools

[natelust]

This commit adds an interface that can be used to represent multi-dimensional data like images, or stacks of images. It uses an industry standard interface to ensure analysis tools can work with a wide variety of data types from numpy arrays to pytorch models.

Did you intend to add this (and associated class below) on this ticket?

[natelust]

No, when I switched branches it looks like my editor thought it was code still active in the buffer or something

[leeskelvin]

What's the purpose of the "\ s"? Is it an attempt to preserve a space? Is it needed? And will it work? I'd imagine you may need to double-escape "\" here to make this work.

[natelust]

In the past this has been how you have a link (to Tensor in this case) and have an s at the end of it. You can't include it in the quotes or sphinx can't find the object. the \ is an escape sequence on the space that says don't include this in formatting.

Do you need to add reference to Tensor here?
