websocket Read Limit Fix
This fix addresses a potential denial-of-service (DoS) vector that can cause an integer overflow in the presence of malicious WebSocket frames.

The fix adds additional checks against the remaining bytes on a connection, as well as a test to prevent regression.

Credit to Max Justicz (https://justi.cz/) for discovering and reporting this, as well as providing a robust PoC and review.
