Summary:
Introducing a Flipper WebSocket client implemented in C++.
The requirement came from Spark AR (Skylight) as they have a macOS/Linux/Windows clients.
For reviewers:
- This is an implementation of the existing FlipperSocket interface. Effectively, the only type that needs to be reviewed is WebSocketTLSClient.
- BaseClient defined a base class for WebSocketClient and WebSocketTLSClient.
- WebSocketClient is a simplified version of WebSocketTLSClient as there's no TLS configuration.
