NPU Driver Installation
Install the required NPU driver for AMD Ryzen AI processors

## Why do I need the NPU driver?

Lemonade uses Ryzen AI Software and FastFlowLM software to access the NPU (Neural Processing Unit) on AMD Ryzen AI processors. New releases of these engines often require an updated NPU driver. The NPU driver is required for AI acceleration and enables hardware-accelerated inference for machine learning models on compatible systems.
Note: The minimum required NPU driver version for RyzenAI 1.6.0 is `32.0.203.280` and the FastFlowLM recommended driver version is provided here.
