Add `StreamMessage.of(inputStream, bufferSize)`

It would be nice if we provide a way to convert an InputStream to a StreamMessage<HttpData> that splits the binary by the bufferSize.

static StreamMessage<HttpData> of(InputStream inputStream, ByteBufAllocator alloc, int bufferSize) {...}

@minwoox Could I try my hand at this?

This would return a new class (which implements StreamMessage) that would be capable of taking an InputStream and return bufferSize bytes when demand() is invoked

Yes, exactly. 😄 You might want to take a look at https://github.com/line/armeria/blob/master/core/src/main/java/com/linecorp/armeria/server/file/StreamingHttpFile.java because it’s implemented in that way.
