How to increment offset in FeedMe 2.0
Received from the developer on Twitter:


  There’s no way to handle pagination or offsets automatically yet I’m
  afraid. You’d have to roll your own solution to handle this at the
  moment


I've been thinking about creating a plugin that polls the API and triggers a FeedMe task with a custom offset parameter. It would also need to record the status of the task once it's complete and the offset for the next 100 records as well.
