Description

Currently, the Gaussian Blur functionality is only implemented for f32 images.

It would be beneficial to add support for u8 images as well. This would enable broader usage scenarios and improve the usability of the Gaussian Blur functionality for typical image processing pipelines where u8 images are common.

Contributor guide

Research direction
Examine the existing Gaussian blur implementation for f32 images to understand the algorithm and kernel handling. Then, adapt it for u8 images, considering integer arithmetic or scaling. Check how other similar operations (e.g., convolution) handle u8 types in kornia rs.
