Summary:
This diff ensures that all operations on the socket are put into a serial background queue, including delegate callbacks.
All operations are executed asynchronously except disconnect, which is made synchronous as to guarantee no resources are accessed after the call.

Summary:
This change moves the existing serialiser from FlipperWebSocket to FlipperURLSerializer.
The serialiser can be shared with Android as it no longer has any iOS dependencies.

Summary:
This change removes ourselves as a delegate before closing.
SocketRocket uses its own internal async queue to perform most operations.
After a disconnect, we don't expect to receive any more delegate calls as the handlers may contain references which may have become invalid.
So, removing ourselves as delegates will ensure that we don't get called after a disconnect.
For sanity, we are also taking a copy of the message handler instead of a reference to it.

Summary:
Trigger a manual disconnect on deallocation. This was done automatically for us when the underlying socket gets released. But, this gives a bit more visibility and control onto exactly when this is going to take place.
Additionally, do not clear the message handler when a message is received.
It is not required as sendExpectResponse is one time called only used for certificate exchange. If this takes place again, a new handler will be set anyway.

Summary:
Addresses an issue with the connect and disconnect sequence.
Both, connect and disconnect should be performed 'synchronously' instead of being queued in the connection event thread.
Events should be queued in the connection event thread instead.

Summary:
This change makes WebSockets the default for Flipper on iOS.
Having said that, we are introducing some logic to deal with clients connecting to older Flipper Desktop versions.
The mobile client will first attempt to connect via WebSocket with the Desktop. This connection can either be secure or insecure. If that fails, it will attempt to connect via RSocket.
Connection failure logic:
The mobile client will attempt to connect up-to 3 times via a WebSocket. If it fails to connect, then the socket provider is switched to RSocket.
As before, the mobile client will attempt to connect up-to 3 times via a RSocket. If it fails to connect, then the socket provider is switched back to WebSocket.
Process repeats until a successful connection is established.

About SocketRocket and Cocoapods
A decision had to be made about whether to define different sub-specs, one for RSocket and another for SocketRocket.
I've opted to keep the podspec as is because:
- Keeps pod consumption as is.
- Makes easier to switch implementations using GK.
- There's no intention to keep RSocket going into the future. So, there's no point in creating a sub-spec only to remove it in the future.
- SocketRocket is a relatively small library so is not contributing to a significant increase in binary size.
If, as reviewer, you consider a subspec makes more sense, then feel free to reach out to discuss.
