Pass Uint8Array from/to native module

[motiz88]

Given recent developments in JavaScriptCore, it's reasonable to expect that the React Native bridge will eventually support marshaling typed arrays efficiently to and from native methods (see for example facebook/react-native#1424). When that happens, we will want to use this capability for send/onmidimessage, so we can move MIDI data back and forth in native-backed Uint8Arrays without extra allocation/copying.

Agreed.

It would be nice indeed, anything blocking on that still?

I haven't worked on this module in years since I never went ahead with the project that required it. Consider it a proof of concept. That said, I'm not sure what the current state of things is in React Native, but I think I've seen native Blob support mentioned at some point, so this might warrant looking into again.

I see, thanks!
