Feature: run CI also on ARM 32/64 CPU
Is your feature request related to a problem? Please describe. Many SBC bitcoin node distributions use electrs, but our CI only builds & tests it on x64 CPU. Currently, the code has a few workarounds to build/run on ARM-based devices, but it's not automatically tested.
Describe the solution you'd like Something similar to https://github.com/rust-bitcoin/rust-bitcoin/blob/a961ab452657a2e94925632747a1794b768c17a6/.github/workflows/rust.yml#L97-L117.
Would prefer to use Rust from the packages to test saner scenarios.
Also, consider using https://github.com/marketplace/actions/arm-runner.
https://cirrus-ci.org/ seems to support free ARM builders for open-source projects.
Done in #900.
