Use msgpack instead of json if the client ask for it

[TriForMine]

Hi,
It would be really awesome if discord could support sending msgpack instead of json if the client want it.
(Would be optional to avoid breaking existing implementation of the api)

MessagePack in a lot of languages is faster, lightweight and doesn't need a gzip compression. That would probably increase performance for both client and server.
In terms of sizes, it would be the same than gzip compressed json, but that requires one more step for serialization/deserialization. And that would also allow to save a lot of bandwidth.
It could be used for both gateway and rest.

Messagepack is already used in a lot of known libraries like python etc. And is fairly production ready.
Discord could even use a custom extension type for snowflake. So javascript could for example parse that value into a bigint directly, and other languages could use string if they don't support bigint.

We are happy with JSON right now. I have not seen evidence that JSON deserialization speed or payload size is a problem for most bots
