Add vulkan nim generator
A quick attempt at a vulkan nim generator. The code is quite ugly but it seems to get the job done. I'll ask for feedback regarding the bindings to the nim community, so feel free to ignore this until the bindings are properly reviewed. Also, any comment on how to improve the code is welcome.
Thanks for your work, currently busy and the question I formulated in https://github.com/Dav1dde/glad/issues/302 kept me busy a bit, input welcome especially from contributors.
I will go over it when I get a minute.
The best way to move forward would be to develop this as a plugin. I cannot maintain all these languages with all the support they deserve. I will happily include plugins on the websites.
