Dynamic federation hangs at completion

[trevorhardy]

Describe the bug
The dynamic federation example has a late-joining federate that is able to join the co-simulation but when the co-simulation ends and the federates all try to leave, the co-simulation hangs.

What is the expected behavior?
Federates would be able to leave the co-simulation at its completion.

To Reproduce
Example has been committed in the HELICS-example repo here.

Environment (please complete the following information):

• Operating System: Mac and Windows
• Language Extension: Python
• what compiler or setup process did you use
• HELICS version: 3.4.0

Run to see log files. All federates have reached the end of their simulated time and are hanging when trying to leave. Battery.py has been used for debugging up to this point and logs the results of a global_time_debugging while making an asynchronous time request for h.HELICS_TIME_MAXTIME (which all other federates are also doing).

@phlptp do you think this will be addressed in the upcoming release?
