Enable building on modern macOS; add missing vendor matching for macOS #46

Hi,

I don't really know what I am doing, but I was trying to run usb-relay-hid on an M1 based Mac which did not work right.

So I updated the Xcode project to work with modern macOS (only with modern macOS, I'm afraid)

Then I debugged the issue and saw that IOKit was giving me an kIOReturnExclusiveAccess error.

I figured this was because usb-relay-hid was querying for all USB devices and not yet filtering by vendor ID. So I added filtering by the vendor of my device (0x05df, www.dcttech.com).

I'm not sure if what I did is an improvement across the board, but it works for me.
