We all know that the fact that MRtrix3 automatically by default permutes & flips axes to make any imported image approximate transverse can cause confusion for users and developers alike.

One consequence of #1843 is that the axis permutations and flips that were applied are stored in the image header. This means that it is possible to reverse those operations to replicate the on-disk strides & transform, regardless of image format.

Reporting this information in mrinfo would potentially resolve a lot of confusion.
