Patch R02_3.00.06_FasterRawValuesMOD.bin into an optimized accel-only firmware.

This script takes the FasterRawValuesMOD firmware and applies three optimizations:
1. NOPs the PPG (photoplethysmography) driver initialization — frees CPU cycles
2. NOPs the Blood and HRS BLE notification sends — only accelerometer data is sent
3. Sets the timer config byte to 0x04 for maximum stable rate (~40Hz)

The result is a firmware that streams accelerometer data at ~40Hz without crashing,
