This commit introduces two main enhancements:
1. Adds an `auto_handle_wsol` parameter to `PumpSwap` buy/sell functions. When enabled, the SDK automatically manages the wrapping of SOL to WSOL and unwrapping back to SOL, simplifying client-side logic.
2. Enriches `PumpSwap` gRPC buy/sell events by parsing transaction instructions to include token mints and account addresses, providing more context for event consumers.
This commit refactors the `copy_buy_with_tip`, `sell_by_percent`, `sell_by_amount`, and their `with_tip` variants within the `PumpFun` struct.
The functions now accept parameter objects (`BuyWithTipParams`, `SellParams`, `SellWithTipParams`) instead of a list of individual arguments. This change improves code modularity, readability, and allows for dynamic dispatch to the correct protocol implementation (PumpFun or PumpSwap) based on the provided protocol parameters.
