Bedrock Edition Map Improvements

Adding the Banner Marker Feature to Bedrock would be incredibly helpful for not only single player (if you have a large amount of scattered builds) But also Realms/Servers as well.

• You usually to use 3/4 maps to see village builds and roads on a map, otherwise it's a singular pixel or two. 
• For example, I have a large farm area that's about 30 by 60 (Very roughly) blocks that shows up as only 3x6 pixels on a 3/4 map.
• This especially becomes an issue whenever a realm/server brings towns or nations into the equation, so if you have a bunch of small cities or nations that you need to remember instead of just 1 base it gets even worse. It isn't very realistic or pleasant-looking to have large layers in the sky, signs; bridges, roads, and rails, or large areas of paths just to make a mark on a large map.

A simple way to solve this issue would be copying the "Map Marker" feature from Java and editing the code if need be to suit the natural differences between Bedrock and Java.

If needed, changing the Banner and Text sizes is always an option too.((Potentially Making the Texts & Banners Larger an Accessibility Setting, for example.))
