Title: Adding an rthook for ctypes so the app can find the usb dynamic libs at runtime.

I needed this rthook to get my program working on the Mac. Pyinstaller bundles the libusb dylibs correctly, but ctypes can't find them at runtime. This rthook fixes that and allows my application to find the dylibs.
