Minimum changes for occupancy API

[Jark5455]

Hello,

Here is a draft pull request for #102. These are only the minimum changes (no docs, default parameters, etc..)

Look good to me, can you run cargo fmt and then I can merge

I believe it is failing because of a change that isn't made by me. The Cudnn::new function is returning an Arc to a Cudnn handle even though it shouldn't be able to since Cudnn handles are not thread safe.

here is the problematic code

According to nvidias cuDNN developer guide

"The cuDNN library is thread-safe. Its functions can be called from multiple host threads, so long as the threads do not share the same cuDNN handle simultaneously."

Actually you don't need to fix the Arc, I can fix that separately - Can you revert that change but keep the cargo fmt? I will manually merge even though the piplines fail 😄

Sorry about that, im struggling with git a bit, I think its good now.
