Generate Multipart Stream for transient document upload

Thanks to @trip-somers for the solution.

$file_path = '/path/to/local/document';

$file_stream = Psr7\FnStream::decorate(Psr7\stream_for(file_get_contents($file_path)), [
    'getMetadata' => function() use ($file_path) {
        return $file_path;
    }
]);

$multipart_stream   = new Psr7\MultipartStream([
    [
        'name'     => 'File',
        'contents' => $file_stream
    ]
]);

$transient_document = $adobeSign->uploadTransientDocument($multipart_stream);
