Updates for DAPHNEEth readout type scan test using asset file

[wesketchum]

Description

Addresses issue #263 by introducing the use of a DAPHNEEth asset file in readout_type_scan.

Requires PRs from daqconf and fdreadoutlibs, and should also have fdreadoutmodules pulled down for testing. A yaml recipe file is

recipe_name: fake-pds-eth-conf
daq_release: NFD_DEV_260831_A9
daq_release_type: nightly

If that is copied into a fake-pds-eth-conf.yaml file, then after setting up dbt,

dbtx-create-workarea-from-recipe.py --use-ref fake-pds-eth-conf.yaml

will create a working area. After builidng/setting up, test by doing

daqsystemtest_integtest_bundle.sh -k readout_type_scan

and should see the DAPHNEEth test passes.

Type of change

• Documentation (non-breaking change that adds or improves the documentation)
• New feature or enhancement (non-breaking change which adds functionality)
• Optimization (non-breaking change that improves code/performance)
• Bug fix (non-breaking change which fixes an issue)
• Breaking change (whatever its nature)

Testing checklist

• Unit tests pass (e.g. dbt-build --unittest)
• Minimal system quicktest passes (pytest -s minimal_system_quick_test.py)
• Full set of integration tests pass (dunedaq_integtest_bundle.sh)
• Python tests pass if applicable (e.g. python -m pytest)
• Pre-commit hooks run successfully if applicable (e.g. pre-commit run --all-files)

Further checks

• Code is commented where needed, particularly in hard-to-understand areas
• Code style is correct (dbt-build --lint, and/or see https://dune-daq-sw.readthedocs.io/en/latest/packages/styleguide/)
• If applicable, new tests have been added or an issue has been opened to tackle that in the future.

This looks reasonable to me. I've confirmed that the readout_type_scan_test continues to run fine with these changes. And, config diagrams generated from the integtest config for the DAPHNEEth part of the RTST show the expected difference. I'm a little surprised that the size of the DAPHNEEth fragments are very similar before and after these changes, but maybe that is just based on good tuning of the tick difference.

I expect it comes down to the similarity of the setup of the distributions of the timestamps between the purely fake data mode and the data pulled from the asset file.
