This commit introduces support for the arm64 architecture by:
1. **Updating the Dockerfile:**
* The `exporter/Dockerfile` now uses the `TARGETARCH` build argument to dynamically determine the correct path for `libiperf.so.0`. This allows the same Dockerfile to be used for building both `amd64` and `arm64` images.
2. **Modifying GitHub Workflows:**
* The CI workflow (`.github/workflows/ci.yaml`) and the Release workflow (`.github/workflows/release.yml`) have been updated to build and push multi-architecture Docker images (`linux/amd64` and `linux/arm64`).
* This involves adding the `docker/setup-qemu-action` for cross-compilation and specifying the target platforms in the `docker/build-push-action`.
3. **Helm Chart:**
* No changes were required for the Helm chart as the image tag will now point to a multi-arch manifest, and the default iperf3 server image (`networkstatic/iperf3:latest`) is assumed to be multi-arch. Node selectors in the chart are not architecture-specific.
These changes enable the deployment of the iperf3-monitor on Kubernetes clusters with arm64 nodes.
