Fast LENS

[matteobecchi]

Requested Reviewers: @SimoneMartino98

LENS computation is re-implemented from scratch, using a format that allows parallelization with numba to make it faster.

The parameters centers, selection, respect_pbc and n_jobs have been added to all the Trj methods for which they are relevant and that use some function of the lens module.

Additionally, some general improvements in the pytest formatting have been done, and annoying warnings from MDAnalysis every time a universe is initialized have been silenced.

Super clean job !

just minor comments, plus i would add a new issue to manage non-cubic boxes (for lens and number of neighbors).

then i'm considering solved:

• #129
• #125
• #121
• #119
• #18

There is always this picture re-uploaded while we do some update; should we ignore that in the gitignore ?

[matteobecchi]

I wonder why is always that picture. Maybe there is some uncontrolled random number generation behind it?

Might be that png have time stamps and it is remade each time. You can add it to gitignore now that the file already exists, it should not delete the file.
