Exposes a single function, which has the same api as child_process.spawn().
Returns a Promise with .child set to the spawned child process. The Promise resolves to the buffered output of child.stdout in the form of a [BufferList] object.
If there was an error, the Promise rejects with an Error object, which has the following extra properties:
* code the error codestdout
* the buffered output of stdout in the form of a [BufferList] objectstderr
* the buffered output of stderr in the form of a [BufferList] object
Note that child.stdout doesn't exist if options.stdio === 'inherit', so the Promise resolves to ''.
