Change max_file_size_test TP_rate_per_channel to 4.75.

[xinyue-uoft]

Description

DUNE-DAQ/datahandlinglibs#144 has adjusted TP_rate_per_channel logic to address issue DUNE-DAQ/datahandlinglibs#74. This has caused max_file_size_test to fail with an additional record file (7) instead of 6. In order to fix the test, base rate is reduced from 5 to 4.75.

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)

Adjusted max_file_size_test passes.

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.

LGTM. The max_file_size_test now runs with no complaints.
