Add initial CI pipeline

This merge request resolves #3, by adding an initial CI pipeline. This pipeline currently tests the installation and the parsing of the message (separating and concatenating the data), which is the code in the messageparser.py.

More advanced tests will soon be added once #1 has been resolved to enable a test environment that can run in a CI pipeline.

Currently, the test:python3.10 has been allowed to fail since the wheel for confluent-kafka including librdkafka has not been created for python 3.10 yet: https://github.com/confluentinc/confluent-kafka-python/issues/1219
