Add get_report_descriptor

[maniwani]

hidapi recently added HID report descriptor parsing in libusb/hidapi#451 for the (upcoming?) 0.14.0 version. Can it be made accessible here?

I am going to wait for the official update of the C library, but when it eventually releases I will add the new function.

You can use the branch https://github.com/ruabmbua/hidapi-rs/tree/hid-report-descriptor for now as a direct cargo git dependency. Tested it on linux ans seems to work.

Thanks!

hidapi 0.14.0 has been released 🎉

I will look into updating and then rebasing the hid-report-descriptor branch onto master. Although it probably has to wait until end of next week when I have time again and can access my workstation for testing on all the different platforms.
