Copying files from one zip to another.

[dmitry-karpik]

Could you implement a copy method file from one zip to another.

For example:
I have zip metadata from salesforce, I would like to save each file in a separate attachment. When we use getFile() we convert it to Blob then then back to zip. And I get the 'CPU LIMIT TIMEOUT' error, but if there was a copy option, I think it would work.

Thanks!
