feat: Add async client method to subscribe to display group events (#353)

* feat: Add async client method to subscribe to display group events, supporting corresponding message types and including an example.

* fix(client): prevent panic on short display group messages

Subscribing to display group events could panic if TWS sent a message with fewer than 4 fields (e.g. when the group is empty).
This change adds a length check before accessing the contract info field at index 3.

Fixes index out of bounds panic.

* fix: add unsubscribe support and message validation for group events

- Add cancel_fn to send UnsubscribeFromGroupEvents when subscription dropped
- Validate incoming message type is DisplayGroupUpdated
- Add set_cancel_fn and has_cancel_fn methods to Subscription
- Add tests for cancel function and message type validation

* fix: use recommended port in example, add warning for short messages

* refactor: extract display groups encoders/decoders to separate module

- Create display_groups module with common/encoders.rs and common/decoders.rs
- Move encoding/decoding logic out of client/async.rs
- Add unit tests for encoders and decoders
- Feature-gate module for async only

* fix: use TWS port for display groups example (Gateway doesn't support display groups)
