Switch to a fork of DDHidLib

Corrects this warning:

    DDHidLib/lib/DDHidQueue.m:27:9: warning: non-portable path
          to file '"DDHidEvent.h"'; specified path differs in case from file name on disk
          [-Wnonportable-include-path]
    #import "DDHIdEvent.h"
            ^~~~~~~~~~~~~~
            "DDHidEvent.h"
    1 warning generated.

I had made the change locally a long time ago, but it's now committed
and published publicly.
