We are considering trying out target-determinator in Diff CI, but we have some performance constraints.

Can we add CLI that supports taking in an already computed hash file from master to avoid git checkout base commit and perform a cquery on the base commit for comparison? This is a feature in https://github.com/Tinder/bazel-diff#get-impacted-targets-command

With this feature, we can compute hash file in master CI and reuse the result in diff CI and save us seconds to minutes.
