v1.6.0

• Some flows don't need to wait for Aquarius to update when registering assets. Not waiting can save 30 s - 10 min. The changes here support that.
  • The OceanAssets method create(), now takes two more arguments: (a) whether to wait for Aquarius, and (b) whether to return just ddo_asset versus a tuple of (data_nft, datatokens, ddo_asset).
  • The OceanAssets methods create_url_asset(), create_graphql_asset(), and create_onchain_asset() use that change. Now, they (a) let the user choose whether to wait for Aquarius, and (b) return a tuple of (data_nft, datatoken, ddo_asset).
  • The changes above are a fix for issue #1007 (b).
