Ability to convert the session files back to the Session Manager format

[MagicalDrizzle]

I am on a old computer and using Pale Moon, which doesn't support WebExtensions, and I'm forced to use Session Manager. I have a couple of exported session files from this extension that I'd like to import back in. Since the extension already support the conversion of the Session Manager format to yours, I believe simply converting back would be similarly trivial.

Yes I second this request. Alot of users including I, still use Session Manager. A way to convert back to it would be helpful.
