I've also updated ESP-IDF Docker images: <https://github.com/EmbeddedNim/dockerbuilds/pkgs/container/esp-idf>
Nesper itself now uses these Docker images: <https://github.com/elcritch/nesper/blob/devel/.devcontainer/Dockerfile.build> Unfortunately, until nim-lang.org starts putting up ARM64 releases it's too fiddly to build ARM versions. Maybe once choosenim native ARM support gets merged I'll be able to create ARM64 images for running on Macs.
