bilateralFilterAsync function
BilateralFilter applies a bilateral filter to an image.
Bilateral filtering is described here: http:///www.dai.ed.ac.uk/CVonline/LOCAL_COPIES/MANDUCHI1/Bilateral_Filtering.html
BilateralFilter can reduce unwanted noise very well while keeping edges fairly sharp. However, it is very slow compared to most filters.

Implementation
Future<Mat> bilateralFilterAsync(Mat src, int diameter, double sigmaColor, double sigmaSpace) async =>
cvRunAsync(
(callback) => cffi.BilateralFilter_Async(src.ref, diameter, sigmaColor, sigmaSpace, callback),
matCompleter,
);
