A zero-CPU-Overhead OV7725 Camera Streaming Library for RP2350 (90fps)

A new Arduino library, OV7725_CPUfree_Camera, enables image capture from OV7725 cameras on the RP2350 microcontroller without CPU overhead, using DMA and PIO automation. This allows both CPU cores to focus on AI/ML and real-time processing tasks while streaming at a fixed 90 FPS.
