getCompiledApi doesn't appear to be implemented

[thomasjwebb]

I don't see any entry in node-midi.cpp for getCompiledApi so there doesn't seem to be a way for me to see which apis are available and specify (say I want JACK vs. ALSA). Am I missing something or is this just something that needs to be added? I'm not that versed in node-gyp but I can try implementing it if it's really missing.
