Minor fusion refactoring

[lintool]

Renamed yaml and tweaked dependent filename.

To repro, first generate dependent files:

python src/main/python/run_regression.py --index --verify --search --regression beir-v1.0.0-robust04.bge-base-en-v1.5.flat.onnx
python src/main/python/run_regression.py --index --verify --search --regression beir-v1.0.0-robust04.flat

Then fuse:

python src/main/python/run_fusion_regression.py --regression beir-v1.0.0-robust04
