MMGP: GPU Memory Management

mmgp (Memory Management for the GPU Poor) is a low-level Python library for direct GPU memory management, primarily designed for use with `tinygrad`. It provides functions for allocating and freeing raw memory on the GPU. As of version `3.7.6`, it offers granular control over GPU resources, allowing for efficient memory handling in performance-critical applications. Its release cadence is irregular, often aligning with `tinygrad` development.
