Module websocket 

Python bindings for the BitMEX WebSocket client.

PyBitmexWebSocketClient wraps the Rust BitmexWebSocketClient and adds an instrument cache at the Python boundary. The inner client is a pure network component that emits venue-specific types; this wrapper parses them into Nautilus domain objects before passing them to Python callbacks.

The instrument cache is shared via Arc<AtomicMap> so that:

• Python can inject instruments at any time via cache_instrument.
• The spawned stream task reads from the same cache for parsing.
• Instrument table messages from the venue update the cache automatically.
