Multicodec-packed uses "protocol tables" to agree upon the mapping from one multicodec-packed code (a single varint). These tables map an `<mcp-code>` to a full [multicodec protocol path](./README.md#the-protocol-path). These tables can be application specific, though -- like [with](https://github.com/multiformats/multihash) [other](https://github.com/multiformats/multibase) [multiformats](https://github.com/multiformats/multiaddr) -- we will keep a globally agreed upon table with common protocols and formats.
