This PR creates a new file that contains a wrapper around the oidn buffer adding `as_raw` and `from_raw` functions for both the device and the buffer so that users can...

Should oidn expose the OIDNBuffer in a safe way?

1

Currently oidn provides `OIDNBuffer`, but we do not expose this, instead only providing vectors to interact with the api. It could be useful to expose a wrapper around these (and...
