Refactor the pyramid part is done. More need to be refactored will be done when I work on other modalities. Now it also lazy loads the files instead of loading all at once.

I went (very very) quickly thourgh it and it looks fine.

The only question I have, and I think we'll have to check with Nate, is how the channels of the input file map to its spatial axes. Say differently, each voxel contains an orientation vector and we need to understnad in what referential this orientation vector is. In the output zarr, we'll want the first channel to correspond to dimension "x", the second channel to dimension "y", etc.

Probably we can revisit that later? We can open an issue and merge this first.
