New basic worker example
Create the simplest worker (that can communicate with an Arkindex instance, but does not rely on arkindex-base-worker).
This worker will:
- retrieve its configuration through the
ARKINDEX_WORKER_RUN_IDenvironment variable - loop over process elements
- create a transcription with content
Hello world!,confidence=1.0on each of them.
The code will be stored in examples/standalone/python. Document extensively the Python code, and add a Readme to explain how this worker can be used.
