The new client certainly has backpressure, it uses the mdn streams interface and pauses everything after a member is found and resumes when a new member is expected. If you need any other features in the new client that prevents you from changing, please let us know! @erikap @madnificent |

This PR contains an attempt to take advantage of Node's built-in backpressure in streams (i.e. buffering in case of a slower consumer) instead of trying to manage it ourselves. It also includes an exponential backoff mechanism to retry failing requests.
This PR should not be merged as such. We've removed some code (like for example the
pausedflag) which may be considered a breaking change (although it looks like an internal to us) and didn't extensively test all different kinds of representations. Given that a new implementation is being worked on in https://github.com/TREEcg/ldes-client, it does not seem appropriate to us to further clean up and elaborate on this PR, but we wanted to indicate what our issues have been with this client so that they can possibly be taken into account in the new implementation.Co-author: @madnifcent
