v2.0.0

Release maze_generator version 2.0.0

Breaking Changes

• Signature of Generator::generate(…) hase been changed.
  It now returns a Result<Maze> instead of a maze directly. This is a side effect of the fact that all internal calls
  to unwrap(), expect(…) and panic!(…) have been removed.
  Instead, those error cases now properly propagate instead of killing the application.

Misc

• Clippy lints have been enabled, configured and multiple resulting warnings have been fixed.
