Can you add 'nanquantile' to this project?

I would like to suggest optimizing the performance of the nanquantile function in NumPy. Although it is a commonly used function for handling arrays with missing values, its execution speed is relatively slow. Enhancing the performance of nanquantile would greatly benefit computations involving arrays with NaN values.

Hello @sysy007uuu, currently not enough bandwidth to add more features, but feel free to propose a PR! :)
