transform - can be used to resample an image into any other space.

compressed voxelwise EVs

- (..., 3, 3) full diffusion tensors
- (..., 6) unique components
- tuple of eigenvectors & eigenvalues

There should be full test coverage of these new functions,
but coverage.py is currently not working for me, so not 100% sure.

are read-only, so we needd to create copies.

guessing the data type of a file/directory path.

VoxelwiseEV and VoxelwiseConfoundEV classes share a common base class.

this is all handled by nibabel. Also never keeps its own ref to file object.
Image.save always saves to a temp file, then moves that to the destination -
avoid any problems with mmap/indexed_gzip.

reduce the number of series that need to be loaded.
