Create component to display remote video source

[hugoponthieu]

Issue linked to #17.
Implement display and interpretation of remote audio/video sources.
The component will be able to read what's happening in the websocket. Everytime the "audio" message happens, it decodes the payload to display the audio/video.
It just need a connected user entity to work, in order to display from who is coming the feed and to manage the socket:

interface RemoteFeedProps {
	member: ConnectedUserEntity
}

export interface ConnectedUserEntity {
	id: string
	username: string
}
