* Use pipes instead of queues.
Possible solution for #68
* Handle ConnectionRefusedError
* Close corresponding pipes on shutdown
* Abstract classes for plugins.
* Add github workflows
* Use pytest for github workflow
* Add Windows/Mac workflows
* Use os.matrix
* 3.8 and 3.9 probably dont exists yet
* Do not fail-fast, also python 3.5 seems to be throwing syntax error for typing
* autopep8
* Disable windows-latest workflow which seems to hang
