[Feature] Build M1 Mac ARM64 Images

Docker images are currently built for intel/amd only.

It would be nice to have M1 mac Arm builds

## How to do this

1. Use [buildx](https://www.docker.com/blog/multi-arch-images/) with docker. It natively supports multi platform builds
2. Add the platform to the github action

Here is [an example](https://github.com/spuder/stl2origin/blob/master/.github/workflows/dockerhub.yaml#L33)

```
name: Build and push
uses: docker/build-push-action@v2
with:
context: .
platforms: linux/amd64, linux/arm64
push: true
tags: spuder/stl2origin:latest
```
