Business Context
A manufacturer of high-end optical sensors needs to verify the bit-depth integrity of their output. They are testing a new line of sensors that output raw data intended for 32-bit depth processing. The test aims to ensure the 'condenseImages' action allows explicit control over the output depth and variable copying for traceability.
Data Preparation
Simulation of a single high-precision sensor reading (2x2 matrix). We also include a 'batch_code' variable to test the copyVars functionality.

Run condenseImages requesting a specific depth of 'BIT32' and copying the 'batch_code'.

Expected Result
The resulting 'sensor_image_32bit' table must contain one image row. The 'batch_code' column should appear with the value 'BATCH_X99'. The binary image data should reflect a 32-bit depth encoding as requested.
