Add a sponsor / donation option?

[dogruis]

Hi Damien,

ngdevkit has saved me a lot of time on my Neo Geo project, and I’d like to give something back beyond bug reports. Would you consider turning on GitHub Sponsors (or Ko-fi, Liberapay, whatever you prefer)?

On the repo side it only needs a .github/FUNDING.yml, which puts a “Sponsor” button at the top of the repo page.

I just wanted to ask.
