Device Firmware Upgrade (DFU) Class Function Driver

## Detailed Description

# Module Description

DFU Class Function Driver module. This module contains an internal implementation of the USB DFU Class. User applications can use this class driver instead of implementing the DFU class manually via the low-level USBD_HW and USBD_Core APIs.

This module is designed to simplify the user code by exposing only the required interface needed to interface with Devices using the USB DFU Class.
