Int16 (maybe others) don't deserialize propely

[MarcoPolo]

Repro:

import "package:msgpack2/msgpack2.dart";

main(List<String> arguments) {
  final List<int> data = [0xd1, 0x04, 0xd2];
  print(deserialize(data));
}

Note the 0x04d2 has no leading 1 bit so it should be positive.

It is broken indeed. I have no idea why the implementation uses it's own bitreading instead simply doing byteData.getIntXX. Should be easy to fix though.

I'm moving away from msgpack2. The code is buggy and weirdly overcomplicated, yet not that fast. I published my own msgpack implementation here if anyone is interested.
