[RFC] Ask permission while receiving a file

[blenderskool]

When a file is sent in a room, other peers in the room must get an option to accept/ignore the file receive request initially. If they ignore the file, files would only be transferred to people who accepted the request.

Not sure if it makes sense as Blaze already has rooms in place which would encourage people interested in the files to join a common room and then share the file. If we go with implementing this, few things need to be chalked out:

• How file download acceptance is managed in WebTorrent and WebSocket.
• In group sharing with WebSockets, files are broadcasted to all peers at once. If a peer does not accept/decline the file request, the other peers(who accepted the request) may end up waiting. A timer may be added when the request is shown which would by default ignore the request after the timer runs out. Would need some inputs here.
