feat: add display options to navigation

[illuminati1911]

Adds display options to navigation:

/**
 * Defines the options used by the Navigator for dislaying different elements.
 */
export interface DisplayOptions {
  /**
   * Configures whether destination markers are shown during navigation.
   * If true, destination markers are shown.
   */
  showDestinationMarkers?: boolean;
  /**
   * Configures whether stop signs are shown during navigation.
   * If true, stop signs are shown.
   */
  showStopSigns?: boolean;
  /**
   * Configures whether traffic lights are shown during navigation.
   * If true, traffic lights are shown.
   */
  showTrafficLights?: boolean;
}

• Tests pass
• Appropriate changes to documentation are included in the PR

setDestination could call setDestinations internally with array containing only the given waypoint
