Inefficient bitstream

[beiriannydd]

Whilst this implementation isn't invalid, it isn't in keeping with the principle of msgpack in that it doesn't encode to the smallest bitstream. Efficiencies could be gained by using the smallest storage for the value being stored, not the variable it came from.
An int16(0) is not being represented in bitstream as [0], but rather as [d1,0,0]. The value should be placed into the bitstream as "a number" and then converted back to whatever the developer wants to store "the number" in.

Hi, thank you for pointing this out. I very much appreciate Go test cases to implement the improvements you are proposing.
