Vulkan Video extensions

[hgaiser]

Seeing as the video extensions for encoding and decoding have been finalized, what would it take to implement this functionality in Vulkano?

It seems ash has support for these extensions (as far as I can tell). I am very new to Vulkano, ash and Vulkan in general, but if possible I would like to contribute. My goal is to port the video encoding pipeline in my project Moonshine (game streaming application) to Vulkan Video encoding, which hopefully will mean better cross platform (both hardware and OS) support in the near future.
