Offer a way to contribute financially

[mtlynch]

Thanks so much for your work on this project! I used to use balenaEtcher, but it's not available on NixOS, so I found yours.

Is it possible to make financial contributions to the project?

Consider adding a file called .github/FUNDING.yml that shows people how they can donate.

It can be as simple as:

custom: ["https://www.paypal.me/your-paypal-address"]
