Request to add sherpa-onnx

Please see https://k2-fsa.github.io/sherpa/onnx/index.html for the documentation

It is similar to sherpa-ncnn but uses onnxruntime instead of ncnn for neural network computation.

I've put it on my to-do list 👍

The same team now has pre-builts for many Whisper sizes too!

Wonder how their performance compares.

The above PR removes the 30-second constraint from Whisper, which means you don't have to pad the input to 30-second.

It would be nice if someone could test it and compare the performance with other implementations.
