Suggestion: add CITATION.cff

GitHub supports CFF files which facilitate citing software: you can download BibTex file right from the repository page; and in general it seems to become the common place to put the relevant info instead (or in addition to) README.

For VkFFT, this would be a CITATION.cff file in the repo root with something like:

# This CITATION.cff file was generated with cffinit.
# Visit https://bit.ly/cffinit to generate yours today!

  VkFFT is an efficient GPU-accelerated multidimensional
  Fast Fourier Transform library for
  Vulkan/CUDA/HIP/OpenCL/Level Zero/Metal projects. VkFFT
  aims to provide the community with an open-source
  alternative to Nvidia's cuFFT library while achieving
  better performance. VkFFT is written in C language and
  supports Vulkan, CUDA, HIP, OpenCL, Level Zero and Metal
  as backends.

This is just an example, you can use online generator to modify it or refer to the format schema.

Note, that the "preferred citation" field is not quite supported by the online generator, but works fine on GitHub: see e.g. https://github.com/ExtremeFLOW/neko ("Cite this repository" in the right sidebar). I also used git tag instead of the commit hash for commit: it works well, and it's easier to update when making a new release.
