• Add workflow APIs mesg-js#113

Update library and add workflow compilation

To test:

Create a MESG service like any other (docker is still required)
In the mesg.yml file you can now add your workflow with the following structure:

workflows:
  react-to-event:
    trigger:
      type: Event
      instanceHash: 7vMG8ac7Xd9z4LfEnS6PfUKM3B7x9hFbaf4LM3JTwrBY
      key: eventX
      filters:
        - key: foo
          predicate: EQ
          value: hello
    task:
      instanceHash: 5fzKqHcXDfRvka3KgHqt2yNWyzCFapFY5BqmfrvMdkLZ
      taskKey: taskX
  react-to-result:
    trigger:
      type: Result
      instanceHash: 7vMG8ac7Xd9z4LfEnS6PfUKM3B7x9hFbaf4LM3JTwrBY
      key: testResult
      filters:
        - key: foo
          predicate: EQ
          value: hello
    task:
      instanceHash: 5fzKqHcXDfRvka3KgHqt2yNWyzCFapFY5BqmfrvMdkLZ
      taskKey: taskX
