Since HashMap is unordered, the lockfile produced is non-deterministic because the hashes are serialized in a random order. This is a problem for environments like Nix where we want determinism.
Alternatively, we change
pub hashestoBTreeMapbut we'll have update all the callsites, this is the minimal fix. Let me know what you prefer.
