Twixtools and orientation matrix extraction

[mbertrait]

This PR solves #153 by moving from mapVBVD to twixtools to read Siemens Twix scan files and storing the orientation matrix in the hdr dict.

Nice ! I have made a suggestion for more pythonic code. Also you need to run black/ ruff on your code

LGTM, I think Only Pierre's comments makes sense and some code linting. Ideally we need a test, but thats hard as we need to create dummy data. Lets skip testing this module but maybe @mbertrait can you open an issue if its not already present to track the need for a test?

A minor comment, if you can it could help to just tell here is twixtools is faster or pymapvbvd. It doesnt have to be an extensive test. Careful though, we dont want bad numbers just because data was in cache.

Please also change pymapvbvd to twixtools with the right github link in pyproject.toml
@paquiteau to comment how to specify gitghub link, as twixtools is not released by authors.

I thought about tests but then as you mentioned we need dummy data so I set them aside for the moment.
