Validation error spew on Vulkan
The shaders created by wonnx apparently run into naga/wgpu bugs that cause a lot of validation errors on Vulkan:
[2023-04-18T00:42:44Z ERROR wgpu_hal::vulkan::instance] VALIDATION [UNASSIGNED-CoreValidation-Shader-InconsistentSpirv (0x6bbb14)]

Not really caused by wonnx, but virtually every shader it creates causes an error like this, so I figured I'd document the issue here so people know about it.
You might try upgrading wgpu - maybe that fixes it. We are using an old version (can't update just yet because of an issue with wgpu on the web - see https://github.com/webonnx/wonnx/pull/140, but I guess wgpu@master should work with the minor changes in the PR applied).
