Serializing stream

[dmitry]

How to serialize a stream? For example I want to serialize everything into StringIO object. ZipOutputStream have second parameter in initialize method for that kind of things. We can do something like:

def serialize(output, confirm_valid=false)
  # ...
  Zip::ZipOutputStream.send(output.is_a?(String) ? :open : :write_buffer) # and so on..

So it will be possible to use Package.new.serialize(StringIO.new(""))

More or less duplicate of #3

Hi Dmitry

Just got back from our long New Year holiday in Japan, so please accept my apologies for the delay in getting back to you.
Thanks for the tip on using :write_buffer! Right now I am deep inside MS-OFF-CRYPTO and MS-CBF in an attempt to achieve password protection and encryption for xlsx files. Is there any chance you could send in a pull request that uses an IO buffer?

Hey Dmitry -

I've added in to_stream on the package will will return a rewound StringIO object for the package.
This will be released with 1.0.17
