rocAL Unit test fix

[fiona-gladwin]

Motivation

This PR fixes unit tests for the Python API by correcting data paths, API parameters, and test names to align with updated functionality.

Technical Details

• Updated lens_correction to accept either single parameters (replicated across batch) or per-image parameters
• Fixed the lens correction python API
• Updated test data paths and API parameters to match current implementation for Webdataset test case
• Corrected test output names for clarity

Test Plan

• Need to test the C++ testAllScript.sh and python unit test unit_test.sh, With the latest GoldenOutputs PR

Test Result

rocAL C++ and python unit test :

INFO:root:Failing cases: FishEye_rgb_hip.png, Blur_rgb_hip.png, Blur_gray_host.png, FishEye_gray_hip.png, Blur_rgb_host.png, Blur_gray_hip.png
