New IVs format

First, we need to find a name and a file extension.

We need to create a new format to replace the current one (IVs):

• Contain the Essid (or at least its length if it wasn't found)
• Can handle both WEP (IVs and enough data for PTW) or WPA (handshake). And a file can contain both format (I mean several WEP networks and several WPA networks) at the same time
• More light than IVs
• Versionned, so that it can be easily updated
• Create a class to handle both pcap and the new format at the same time
• Save keystream instead of the encrypted bytes
• Allow keystreams of different sizes up to 1500 bytes (not just first 2 bytes)
