feat: Add support for sameSite field (#628)

Recent browsers (and HTTP) added "sameSite" setting to limit cross site attacks.
Add support for exporting this property from Firefox and Chrome and to export to csv and cookie-editor format.
Also extract new "session" and "hostOnly" properties for cookie-editor format.
Tested on Firefox, Chrome and Chromium.
