Examples, HUGE fixes, test, make it alot smother

Browse Source 
- switch `listen` to async in oder to verify if the bind was successful
- Introduce the following examples
  - network speed
  - chat
  - fileshare
- add additional tests
- fix dropping stream before last messages can be handled bug, when dropping a stream, BParticipant will wait for prio to be empty before dropping the stream and sending the signal
- correct closing of stream and participant
- move tcp to protocols and create udp front and backend
- tracing and fixing a bug that is caused by not waiting for configuration after receiving a frame
- fix a bug in network-speed, but there is still a bug if trace=warn after 2.000.000 messages the server doesnt get that client has shut down and seems to lock somewhere. hard to reproduce

open tasks
[ ] verify UDP works correctly, especcially the connect!
[ ] implements UDP shutdown correctly, the one created in connect!
[ ] unify logging
[ ] fill metrics
[ ] fix dropping stream before last messages can be handled bug
[ ] add documentation
[ ] add benchmarks
[ ] remove async_serde???
[ ] add mpsc
