Removes all tight_layout calls

Matplotlib offers constrained layouts:

https://matplotlib.org/stable/tutorials/intermediate/constrainedlayout_guide.html

which performs better than tight layouts:

At the same time, tight layout is known to trigger certain bugs. For example:

https://github.com/matplotlib/ipympl/issues/335
