suggestion: caching NetworkMessage blocks

[Zbizu]

Explanation of what you want to do that is currently impossible

store part of NetworkMessage object as a variable (preferable in Lua considering that new features use it now)

Desired functionality

improve cache for packets by caching parts of NetworkMessage instead of rebuilding them in systems where returning cached binary data is sufficient (eg. exaltation forge, other server "meta" packets, golden outfit dialog or recently added highscores)

Available workarounds

strings with binary data, ugly looping to move bytes from string to networkMessage

Prior art

local stream = Stream()
stream:addByte(0xFF)

local networkMessage = NetworkMessage()
networkMessage:addBlock(stream)
