Example of stream in Go

[9nut]

I wrote a Go version of the "stream" example to play around with Go bindings. It's here: whisper_stt_go. I'd appreciate any feedback. The performance is OK, but doesn't seem to match the C version in this repo. FYI, it has the same license (MIT); if you think it might be useful, I can submit a pull request to add it to the Go bindings examples.
