filename: the name of the file to be downloaded
options: the download options
returns: the stream

Opens a AsyncOutputStream that the application can write the contents of the file to.

As the application writes the contents to the returned Stream, the contents are uploaded as chunks in the chunks collection. When the application signals it is done writing the contents of the file by calling close on the returned Stream, a files collection document is created in the files collection.

id: the custom id value of the file
filename: the filename for the stream
returns: the GridFSUploadStream that provides the ObjectId for the file to be uploaded and the Stream to which the application will write the contents.

def openUploadStream(filename: String, options: GridFSUploadOptions): GridFSUploadStream
