Decoding an IPNS name that uses DNSLink

[moodysalem]

• decode returns the base58 string for an IPNS + DNSLink name, when we expect the utf8 string
• the content when base58 decoded includes a prefix of the string length
  e.g.
  the uniswap.eth contenthash is 0xe5010170000f6170702e756e69737761702e6f7267
  this points at the ipns url:
  ipns://app.uniswap.org

import {decode} from 'content-hash'
// this is the result of decode in the latest version of content-hash
decode('0xe5010170000f6170702e756e69737761702e6f7267') === '12uA8M8Ku8mHUumxHcu7uee'

if i base58 decode '12uA8M8Ku8mHUumxHcu7uee' and then convert to utf8 i get:
"\u0000\u000fapp.uniswap.org"
