Add support for Network Byte Order

[theaddonn]

Adding support for the network byte order (LE Network byte order and BE Network byte order) would allow us to use this crate in the bedrock protocol and java protocol

What is the difference between "LE network" byte order vs "LE" byte order and "BE network" byte order vs "BE" byte order? From my understanding network byte order is the same as big endian byte order. I haven't worked with Minecraft's server software, so I'd be grateful If you could clarify the differences.
