Can't build in WSL？ about waifu2x-ncnn-vulkan

[nihui]

glslangValidator is too old to compile this shader source
you can download the latest vulkan sdk at https://vulkan.lunarg.com/sdk/home

left one is bundle in android studio,right one install by vulkan's latest sdk(VulkanSDK-1.1.108.0-Installer.exe)
but latest one cannot complie

construct float from uint8 is not allowed in new glsl tool with KhronosGroup/glslang#1832

please try patching waifu2x_preproc.comp file and see if it works

modify waifu2x_preproc.comp as follows

    if (bgr == 1)
        v = float(bottom_blob_data[v_offset * 3 + 2 - gz]);
    else
        v = float(bottom_blob_data[v_offset * 3 + gz]);

    if (bgr == 1)
        v = float(uint(bottom_blob_data[v_offset * 3 + 2 - gz]));
    else
        v = float(uint(bottom_blob_data[v_offset * 3 + gz]));

this work fine for me!
thanks for fix :)
