Cross.toml

# Ref https://github.com/cross-rs/cross/blob/main/docs/custom_images.md#adding-dependencies-to-existing-images
# `cross` is installed in CI via a gh action for speed, which can end up using an old version of cross.
# The version of the cross-image is within each release of cross, so for example I saw the
# 'aarch64-unknown-linux-gnu' image using ubuntu xenial which has an ancient version of protobuf
# Each target has an override to use the latest image off `main`
