Add banners to generated structures to they can be easily added to a map

Not many people know that right clicking on a banner with a map equipped will add a banner icon to the map. If each structure generated with a banner then adding a structure to an in game map would be easy just find it and right click. There is nothing stopping you making your own banner and placing it when you find something of note but having a banner spawn with each structure on world generation would streamline the process and give banners more utility. Update could take place on all platforms but functionality for showing banners on maps in bedrock isn't implemented. There are three levels for depth of implementation: Easy: Just update structure generation to add a coloured banner. Medium: Create a custom banner for each structure and display that on a map when activated. Hard: Create a custom banner pattern only obtainable at each structure and implement as above.
