🔥 Add Websocket Support

[dechristopher]

Is your feature request related to a problem? No

Describe the solution you'd like: I'd like to see the ability to promote a request to a websocket connection and handle pub-sub messaging therein. This is a big feature present in other libraries like gorilla and it would make fiber more competitive.

Describe alternatives you've considered: Use a different web library.

Additional context: None.

Websockets are supported in v1.7.1

app.WebSocket('/echo', func(c *fiber.Conn) {
 // Conn logic
})
