v0.3.0

Version 0.3.0 includes the following changes:

• Conform CID to Codable.
  • You can now use JSONDecoder and JSONEncoder to convert to and from a String object.
  • Revamped Multicodec.
    • There is no longer a registry. Now, you can use one of the pre-built prefixes available.
    • More pre-built prefixes will be added overtime.
    • You can create custom prefixes, but the mechanism to grab it has not been added yet. It will be in the future. At this time, there are no plans to do this. However, you can create the custom prefixes and pass it into the appropriate initializer if you need to.
