package/protozero: new package

Minimalistic protocol buffer decoder and encoder in C++.
Designed for high performance. Suitable for writing zero copy
parsers and encoders with minimal need for run-time allocation
of memory.

Low-level: this is designed to be a building block for writing
a very customized decoder for a stable protobuf schema. If your
protobuf schema is changing frequently or lazy decoding is not
critical for your application then this approach offers
no value: just use the C++ API that can be generated with
the Google Protobufs protoc program.
