Rewrote data reader + writers

I have rewrote all of the code that wrote and read the packet data. now reading uses a reader class that can just call readbool, readint, etc etc one after another instead of needing to chop off data after each read.
Simillarly for the writer I made it so that you can just make a writer and call .writeInt, writebool. etc etc w/o needing to do a += on a bytes object.

Now that my code is cleaned up quite a bit, I want to clean it up some more by moving all of the writing functions into their packet class so you can call something like: StatusResponse_ClientBound.write(PARAMS) to make the code much nicer. after that I will add more play packets to get more feature complete
