* Add generic protocol handler

* Add generic protocol handler to stream muxing pipeline

* Modify conn_handler to only deal with connections

* mplex accept stream architecture changes

* Add create generic protocol handler

* Fix minor bugs

* who would win 4 devs or one not

* Debugging

* rearch with handle_incoming infinite loop, seems to work, needs cleanup"

* passing linting, still needs cleanup

* fixing linting again; code still needs cleanup

* fixing tests; code still needs cleanup

* adding test cleanup and task cleanup, removing prints
