Unhandled type kind objCTypeParam

[JackStouffer]

I'm stress testing DStep with the Foundation headers. I was impressed that NSObject.h worked, but I tried NSArray.h and I got an assert error.

$ ./bin/dstep --version
1.0.2-3-gbc5cda9

$ ./bin/dstep /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/Foundation.framework/Versions/C/Headers/NSArray.h -o NSArray.d -ObjC

dstep: an unknown error occurred: core.exception.AssertError@dstep/translator/Type.d(623): Unhandled type kind objCTypeParam
