CBOR for the binary format?

[bortzmeyer]

The README currently says "Binary Format \ Note: this part is still vaporware \ An optimized binary representation that omits field names and avoids escaping strings." I suggest that designing a binary format from scratch may be some work and, while there are good reasons for creating a new text format like Ziggy, creating a new binary format may be too much. Why not using CBOR, standardized in RFC 8949?

1. It already exists, with a lot of implementations,
2. It is optimized for storage space, and simplicity of parsers,
3. Its data model is very close from the one of JSON so it seems it would be fine for Ziggy.
