Add docker cross-compile for arm64

Browse Source 
This makes use of the docker buildx to cross-compile images for amd64/arm64. It is worth noting that there are ongoing issues with the Go compiler and qemu (used by buildx/buildkit) and the solution I ended up using here was to limit the affinity to `go build`. Better solutions may be forthcoming.

This relates to issue #11 regarding container images built for running on Raspberry Pi.
