Hello.

Please add method World#clearLoadedMapData() (or Server#clearLoadedMapData(), I'm unsure how it works "under the hood") that will clear all loaded map_N.data files from RAM, so the next time the server needs to render the map (for example, if a chunk is loaded in which it hangs on the wall in a frame), it will load the corresponding map_N.data file from the disk into RAM again).

Why I'm need this? To save time when using the site to generate maps from images (e.g. https://rebane2001.com/mapartcraft/). Currently, every time after manually replacing the map file in the world/data folder, I need to completely restart the server. Having one method to reload one map data file or all of the files from disk at once would help a lot. IIRC currently there are no ways to do this. And I need this ability for almost two months now..

If you have any other ideas on how to do the same (clear loaded map(s) data from RAM), please share them.
