Camera API completed 📷 - Added variable resolution settings to `camera.capture` - Added new JPEG quality modes to `camera.capture` - Added panning feature to `camera.capture` - Memory-efficient JPEG header generation for different quality and resolution options - New FPGA side SPI block. Allows for faster and more stable SPI transactions - Improved factory test scripts - Updated Lua test scripts for new APIs ⚠️ **API changes** - `camera.capture{ quality_factor = int }` has been changed to `camera.capture{ quality = str }`. Valid values for `quality` are `'VERY_LOW'`, `'LOW'`, `'MEDIUM'`, `'HIGH'`, and `'VERY_HIGH'`, **Update your Frame automatically using [AR Studio](https://github.com/brilliantlabsAR/ar-studio-for-vscode) or the [Noa App](https://github.com/brilliantlabsAR/noa-flutter)** Want to update manually?
