Introduce --root-dir (#1576)

* windows * Introduce --root-path * lint * lint * Simplification * Add unit tests * Add integration test * Sync docs * Add missing comment to make CI happy * Revert one of the Windows-specific changes because causing a test failure * Support both options at the same time * Revert a comment change that is no longer applicable * Remove unused code * Fix and simplification * Integration test both at the same time * Unit tests both at the same time * Remove now redundant comment * Revert windows-specific change, seems not needed after recent changes * Use Collector::default() * extract method and unit tests * clippy * clippy: &Option<A> -> Option<&A> * Remove outdated comment * Rename --root-path to --root-dir * Restrict --root-dir to absolute paths for now * Move root dir check
