Unable to get it working with stream

[pradeepradyumna]

First of all, this is an amazing creation, I'm loving it.

I got it working with files by passing their path like C:/Files/Sample.docx. However, when I try with Stream object, passing it to TemplateProcessor, it breaks and gives the below exception. Can you help me with this?

System.ArgumentException: Update mode requires a stream with read, write, and seek capabilities.
