Fix docstring formatting

See merge request !780

Introduce a framework to convert from NIFTy to JAX

See merge request !702

Fix the pipeline which was broken in 4f84c82c .

Move some properties of CoordinateChart to actual properties as to
provide doc-strings for them.

Guess a good `depth` based on `min_shape` if none is specified.

Set the new defaults such that the resulting chart is more precise.

Most notably, extend test_refinement_covariance to also test various
refinement parametrizations.

Adapt to the new error message in JAX for failing to transpose a
refinement field.

Fix optimize_kl minisanity evaluation: gracefully handle if latent variable or likelihood operators change between iterations

See merge request !778

Implement a highly efficient refine method for irregular 1D grids.

Instead of a kernel, also accept a set of pre-computed refinement
matrices.

Optimize KL plotting tweaks
