v1.5.1 Direct Streaming

You can now optionally stream content in chunks as they are written to stdout & stderr.

v1.5.0 Utilize StdinPipe

Modify StartWithStdin to utilize StdinPipe from os/exec. Stdin will be returned to the caller and will automatically close unless the underlying program is waiting on stdin. In such a case the caller is responsible for handling the closure of the stdin writer.
