     - Throws: `MoveError.symlinkLimitReached` when the current path already has the maximum number of links to it, or it
                was a directory and the directory containing newPath has the maximum number of links
     - Throws: `MoveError.pathnameTooLong` when either the current path or newPath have more than `PATH_MAX` number of
                characters
