Add ARM64-Support

[Pils10]

Hello,

When I try to run this image on my Oracle Cloud Server (linux/arm64/v8), I get the following error:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
exec /bin/entrypoint: exec format error

So, is there any chance you guys could create an ARM version of the docker image? I (and other Oracle Cloud Free Tier users) would greatly appreciate it.

That's a great idea, sorry about that. I may have time to look at Sour within the next month or so; it desperately needs a better distribution mechanism anyway. Stay tuned.
