Add native MsgPack encoder and decoder

[ghost]

What is the problem this feature would solve?

JSON is large because contains redundant characters and isn't binary

What is the feature you are proposing to solve the problem?

Implement native MsgPack module/functions. MsgPack is fast and small because it's binary and it has structures

What alternatives have you considered?

msgpackr package. It's faster then JSON in Node, but slower in Bun

Would you mind adding a gist with your test to check if anything has improved indirectly with the newer bun versions?
