[Fix] Missing libcudnn_ops_infer.so.8 (Linux), cudnn_ops_infer64_8.dll (Windows), etc.

I am creating this issue for visibility.

I've seen multiple people struggle with this, myself included.

Since I've found the solution, I added instructions on how to solve this problem in PR #183 .

I also streamlined the readme file a bit.

Should I close this issue myself as resolved or would it be more visible to others if the maintainer closes it?
