v0.2.0

Switches multiaddrs from /ipfs/Qm... to /p2p/Qm... by default to reduce confusion.

v0.1.2

• Enforce minimal varint encoding when decoding multiaddrs. See multiformats/unsigned-varint#19
• Ensure codecs fit in 32bit integers for compatibility. We can increase the size, but we'd need to change the Protocol.Codec type from int to uint64.
