Extract createChangesetSpecs from src-cli
Created by: mrnugget
This is part of https://github.com/sourcegraph/sourcegraph/issues/26929 and extracts the createChangesetSpecs
method from src-cli into the lib/batches
package.
I'm not too happy with the ChangesetSpecInput
struct, but I also don't know how to improve it -- yet. But I figured that will come once I use it on the server-side and the src-cli side.
So, if you don't have any ideas on how to improve the input: how about we wait a few days?
