Feature request

Provide a way to abort a long running operation.

Motivation

Many things can take a long time (downloading a multi-gig model on 3G) or are not operating normally (infinite output) and the user may change their mind.

Your contribution

I can look into how to use AbortSignals for the download issue. Not sure what ONNX provides.

Any API suggestion?
