/// Perform a two-hop swap in this Whirlpool
/// This instruction works with both Token and Token-2022.
/// ### Authority
/// - "token_authority" - The authority to withdraw tokens from the input token
///   account.
///
/// ### Parameters
/// - `amount` - The amount of input or output token to swap from (depending on
///   amount_specified_is_input).
/// - `other_amount_threshold` - The maximum/minimum of input/output token to
///   swap into (depending on amount_specified_is_input).
/// - `amount_specified_is_input` - Specifies the token the parameter
///   `amount`represents. If true, the amount represents the input token of the
///   swap.
/// - `a_to_b_one` - The direction of the swap of hop one. True if swapping from
///   A to B. False if swapping from B to A.
/// - `a_to_b_two` - The direction of the swap of hop two. True if swapping from
///   A to B. False if swapping from B to A.
/// - `sqrt_price_limit_one` - The maximum/minimum price the swap will swap to
///   in the first hop.
/// - `sqrt_price_limit_two` - The maximum/minimum price the swap will swap to
///   in the second hop.
///
/// #### Special Errors
/// - `ZeroTradableAmount` - User provided parameter `amount` is 0.
/// - `InvalidSqrtPriceLimitDirection` - User provided parameter
///   `sqrt_price_limit` does not match the direction of the trade.
/// - `SqrtPriceOutOfBounds` - User provided parameter `sqrt_price_limit` is
///   over Whirlppool's max/min bounds for sqrt-price.
/// - `InvalidTickArraySequence` - User provided tick-arrays are not in
///   sequential order required to proceed in this trade direction.
/// - `TickArraySequenceInvalidIndex` - The swap loop attempted to access an
///   invalid array index during the query of the next initialized tick.
/// - `TickArrayIndexOutofBounds` - The swap loop attempted to access an invalid
///   array index during tick crossing.
/// - `LiquidityOverflow` - Liquidity value overflowed 128bits during tick
///   crossing.
/// - `InvalidTickSpacing` - The swap pool was initialized with tick-spacing of
///   0.
/// - `InvalidIntermediaryMint` - Error if the intermediary mint between hop one
///   and two do not equal.
/// - `DuplicateTwoHopPool` - Error if whirlpool one & two are the same pool.
