createTradePtExactOutInstruction

Sells PT tokens to receive an exact amount of SY tokens. This instruction uses createTradePtExactOutInstruction with swapDirection: { sellPt: {} } to sell PT on the CLMM market and receive a precise quantity of SY. The caller specifies the exact SY amount to receive, and an optional maximum PT input constraint can be set for slippage protection.
