Multi-threading with _OpenMP_ for `transform.resize`, `transform.rotate` and `transform.warp` functions. Partial multi-threaded implementation of edge filters:`laplace`, `prewitt`, `prewitt_h`, `prewitt_v`, `sobel`, `sobel_h`, `sobel_v`.

gaussian` and `laplace` filters supported dtypes were extended; extended list of supported interpolation methods for `resize` function
