Cleanup for packaging

The pip packaging procedure copies the carputils/carputils/ to the user/system python path. Therefore, we would like to support the package user by adding carputils/carputils/bin and carputils/carputils/settings.yaml

1. Move carputils/bin to carputils/carputils/bin
2. Add a link carputils/bin to carputils/carputils/bin (for compatibility)
3. Add a settings file path to carputils/carputils/settings.yaml
