====== Post Data to Datastream ======

  - Create a Sensor in farmOS
  - Create a DataStream in / for that sensor
  - Call GET http://localhost/api/data_stream/basic/ to get all basic data streams
  - Response:
    - data includes an array of data_streams
    - ID: res.data[i].id
    - private_key: res.data[i].attributes.private_key
    - name: res.data[i].attributes.name
  - Call POST http://localhost/api/data_stream/<ID>/data?private_key=<private_key> with a Body (in Postman 'raw','json'):
    - {'data': 20}
    - basic data streams can only have one value
    - will look for 'data' in JSON
  - Should give a 201 Created back
  - This value can now be found in Assets>Sensors>(The Sensor you want)>Data stream
