1.0.0.1

This release added GPU acceleration with DirectML. To enable GPU acceleration, set the device id to the GPU index you want to use. Most systems with a single GPU will have a GPU indexed 0.
Using GPU acceleration requires Windows 10 1703 or higher. On some systems, this functionality will yield a black image due to unknown issues.

edit: I also fixed an issue that would cause the app to crash if trying to process a non-square-shaped image.

edit x2: I've noticed a bug that will cause the app to produce a stripped image when processing an image with an alpha channel. A patch has been made to address this issue. I'll release 1.0.0.2 ASAP.
