Message:

FIX: StreamFactory did not set BindingModel.

• we streamed into a default potential instance but this does not set the BindingModel. Now, we use the particle types from that deseralized instance and instantiate a new potential that then also generates the BindingModel.
• added output operator to BindingModel.
• TEST: This fixes the fit-compound-potential regression test case.
