organizeByRepos :: forall a. ActiveRepos -> (a -> RepoName) -> [a] -> Either String [(a, CombineStrategy)]

Sort values RepoName according to ActiveRepos list.

>>> let repos = [RepoName "a", RepoName "b", RepoName "c"]
>>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge]) id repos
Right [(RepoName "a",CombineStrategyMerge),(RepoName "b",CombineStrategyMerge),(RepoName "c",CombineStrategyMerge)]

>>> organizeByRepos (ActiveRepos [ActiveRepo (RepoName "b") CombineStrategyOverride, ActiveRepoRest CombineStrategyMerge]) id repos
Right [(RepoName "b",CombineStrategyOverride),(RepoName "a",CombineStrategyMerge),(RepoName "c",CombineStrategyMerge)]

>>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge, ActiveRepo (RepoName "b") CombineStrategyOverride]) id repos
Right [(RepoName "a",CombineStrategyMerge),(RepoName "c",CombineStrategyMerge),(RepoName "b",CombineStrategyOverride)]

>>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge, ActiveRepo (RepoName "d") CombineStrategyOverride]) id repos
Left "no repository provided d"

Note: currently if ActiveRepoRest is provided more than once, rest-repositories will be multiple times in the output.
