Big Issue: plip can't batch generate pse-files for multiple complex.pdb files.

[FeizhenWu]

Describe the bug

I can successfully run plip command in terminal one by one,
[uxxx@cpu10 test_pdbs]$ plip -f rep_2_160_with_D001-01_4278.pdb -o output --pymol --txt

How to revise this bug?
The issue may be linked to plip.visualization.visualize, where the PyMOL visualization object is not being closed after the .pse file generation is completed.

please revise it.
