Update the installation and usage documentation to reflect changes made
in recent merges. Instructions relating to removed functionality has
been removed. Instructions relating to RS datasets has been commented
out for now as it needs more work.

Lightning API was fixed so these can be removed.

[saliencymap_evaluator] Reimplements interpretability evaluator to simplify code, be less dependent on opencv, improve documentation, and improve type hinting

The obects.inv file from lightning's documentation is missing a lot of
methods, raising errors when building with sphinx. Problematic methods
have been added to the extras.txt and encoded into extras.inv

Auto intersphinx would try to access "https://lightning.ai/lightning-docs/objects.inv" and would be
redirected to "https://lightning.ai/docs/app/stable/objects.inv" instead
of "https://lightning.ai/docs/pytorch/stable/objects.inv"
