USB HID device support for embedded devices

This crate provides minimalistic USB HID support for microcontrollers containing USB peripheral. It works with any microcontroler with usb-device support in HAL.

The support for HID provided by this crate is type-safe. Since USB HID requires complex report descriptors for all reports, only sending of structures that have associated HID report descriptor is permitted.

There is complete usage example in usb-hid-device-example.
