Release 0.15.0

Added

• Implement DNS Discovery as per EIP-1459,
  with ENR records as defined in 31/WAKU2-ENR;
  Available by passing { bootstrap: { enrUrl: enrtree://... } } to Waku.create.
• When using addDecryptionKey,
  it is now possible to specify the decryption method and the content topics of the messages to decrypt;
  this is to reduce the number of decryption attempt done and improve performance.

Changed

• Test: Upgrade nim-waku node to v0.6.
• Breaking: Renamed getBootstrapNodes to getNodesFromHostedJson.
• Minimum node version changed to 16.
• Breaking: Changed Waku.create bootstrap option from { bootstrap: boolean } to { bootstrap: BootstrapOptions }.
  Replace { boostrap: true } with { boostrap: { default: true } } to retain same behaviour.
• Breaking: WakuMessage.decode and WakuMessage.decodeProto now accepts method and content topics for the decryption key.
  WakuMessage.decode(bytes, [key]) becomes WakuMessage.decode(bytes, [{key: key}]).

Fixed

• Doc: Some broken links.
