Test queue size latest latency

[haixuanTao]

Example of error that I will probably need @phil-opp to help me on, which is that the dora queue_size keeps one old message in the queue and not drop all oldest input.

We need to revise our different queues of inputs and make sure to only store the latest input.

This happens in both rust and python, I have added one example of each.

To test

dora start tests/queue_size_latest_data_python/dataflow.yml

cargo build -p receive_data --release
dora start tests/queue_size_latest_data_rust/dataflow.yml
