Implement commands like "getchunkdata"

I started experimenting with MC WebSockets some time ago and I've learned, that there are some (cool) hidden commands that can be executed (such as "listd", "querytarget", "gettopsolidblock", ...) and that some of them return computer readable data (json) like the "gamerule" command.

But there are commands like "getchunkdata", "globalpause" and "transferserver" that don't work (anymore) but would be increadible usefull for external applications that could be used to manage a server or improve gameplay!

Same goes for those events: "ChunkChanged", "ChunkLoaded", "ChunkUnloaded"...

Please add those command & events to the Bedrock Edition!
