* #129 AsyncTcpSource enhancements - retry connection on startup (behavior is configurable) - reconnect if data receiving fails (EOF received) - add Python logging - add unit tests * remove syncronous implementations. * WIP: Refactor packer/unpacker * Refactor type hints and topic handling in console sink. * Remove comma from tcp config enum definitions * Remove references to deleted synchronous classes. * Hopefully stable interface for Packer and Unpacker. * WIP: Working with protocols and generics * Finalized Sink, Source definition. * Rename mqtt source and sink files * Rename mqtt publisher and subscriber. * Fix start function to async. * Update documentation. * Remove recursion from udp source. * rename unpack to unpacker, stay consistent. * Renaming in tests. * Make MqttSource generic. * Configure pyproject.toml to move to uv * Add nox support. * Update documentation with myst-parser and sphinx. * Mess with autogeneration of __call__ signatures. * Add dynamic versioning to hatch * Asyncio wrapper for pyserial. * Add docstrings for serial sink and source. * Refactor config handling (#171) * Removes deprecated "verbose" and "print_std" parameters * Adds class methods for config generation from dictionary or file (yaml or json at this point) * Run-time type checking via __post_init__() function * Add serial dependency. * WIP * Move broker to bin/ * Update docs. * WIP: Need to update docstrings to make ruff happy. * Move source files to src/ * Fix tests for TcpSource. * WIP: Remove old tests. * Fix docstrings in mqtt classes. * Make default tcp unpacker json_unpacker. * No failed tests if there are no tests * Update test pipeline * Update ruff pre-commit * Updated ruff formatting * Format bin/ * Fix type hints * No type checking * Make stop() async * Only test on ubuntu for now * Don't be so strict about sphinx warnings. * Rename TestConf for pytest naming compability. * Install package in editable mode for ci tests. * Update dependencies for docs generation. * Add keepalive and will to mqtt, fixes #112. * Update readme to reflect changes in usage. * Requested fixes for console adapters. * Raise correct errors in unpacker and packer. * Correct logger name for mqtt sink. * Add config options for stopbits and parity to Serial. * Remove exception logging call from yaml parser. * Add comments to clear up very implicit test. * Rename Sink -> Sender, Source -> Receiver. * Rename sink and source in tests. * Fix tests. --------- Co-authored-by: Adrian Weiler <a.weiler@aldea.de>

Configuration of services
MQTT
Programs that use the AsyncMqttSource, AsyncMqttSink, MqttSink or MqttSource are configured via the configuration file located at $HOME/.config/heisskleber/mqtt.yaml
The configuration parameters are host, port, ssl, user and password to establish a connection with the host.
- qos: controls whether delivery of messages is acknowledged or not (see docs for details)[https://docs.oasis-open.org/mqtt/mqtt/v5.0/mqtt-v5.0.html].
- 1: "At most once", where messages are delivered according to the best efforts of the operating environment. Message loss can occur.
- 2: "At least once", where messages are assured to arrive but duplicates can occur.
- 3: "Exactly once", where messages are assured to arrive exactly once.
- max_saved_messages: maximum number of messages that will be saved in the buffer until connection is available.
