Waifu2x-ncnn-vulkan will accept a file as "file.jpg" and output as "file.jpg.png".
Unfortunately, dandere2x wouldn't recognize this, so this function renames each name to the correct naming
convention. This function will iteratiate through every file needing to be upscaled waifu2x-ncnn-vulkan,
and change it's name after it's done saving
Comments:
- There's a really complicated try / except that exists because, even though a file may exist,
the file handle may still be used by waifu2x-ncnn-vulkan (it hasn't released it yet). As a result,
we need to try / except it until it's released, allowing us to rename it.
