Make pixelarts easier to make

Pixelarts with maps are something complicated to do because it takes a long time to complete the entire map with blocks, that's why I thought about making it easier, the idea is the following, give a new use to the cartography table, this can block, duplicate and ZOOM out maps, it would be amazing if you could ZOOM in maps with a amethyst shard (like the spyglass) so fewer blocks would be needed for pixelarts, but if you want something more detailed, you can still use normal maps :D.
