The ixWrapperWithdraw instruction burns tranche LP shares, withdraws SY from the market, and redeems SY back to the base asset.
Usage

user: wallet.publicKey,
trancheSide: TrancheSide.Senior,
lpAmountIn: 500_000_000n, // raw Senior LP units to burn
minBaseOut: 0n, // raw base-token units; set above 0 for output protection
});
const tx = new Transaction().add(...setupIxs, ...ixs);
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);
