Precompilation of dependencies consistently fails with Julia 1.12.0-beta1 (concurrency violation related to Metagraphs and JLD2). Since it's not a priority to debug an issue with a beta Julia version that might not even be specific to this package, I've added - '1.11' to the version matrix and made that a required check rather than - 'pre'.

JuliaFormatter v2.1.0 is out, but it doesn't like import IntervalSets.(..) and a certain multi-line string in routes.jl. It also makes a bunch of reasonable minor changes to other files, so for this PR I'm restricting it to v1. I'll wait to see if it gets yanked right away like v2.0 did and make a separate PR with workarounds if not.
