Mici: Manifold Markov chain Monte Carlo methods in Python

Minor release.

Bug fixes:

• Fixed bug in handling of NaN Hamiltonian values when computing Metropolis accept probability due to min(0, float("nan")) evaluating to 0.
• Fixed CSS styling of progress bar HTML representation to avoid overflow in container div element causing horizontal scrollbars to appear.
• Fixed bug causing sampling stage progress bar to still be displayed when calling sample_chains method with argument display_progress=False.

Packaging changes

• Excluded docs and images folders from sdist builds to minimize download size.
