Does wire do zig-zag / 7bit encoding?

[Moritz Staudinger]

As the title says.
Two really common encoding schemes. Also used by protobuf.

Zigzag is basically rotating an int16/32/64 so the sign bit becomes the least significant bit.
That helps the 7bit encoding to efficiently deal with negative numbers as well.

Does wire do this?
If no, is adding this planned?
