/// Withdraw liquidity from a position in the Whirlpool. This call also updates
/// the position's accrued fees and rewards. This instruction works with both
/// Token and Token-2022. ### Authority
/// - `position_authority` - authority that owns the token corresponding to this
///   desired position.
///
/// ### Parameters
/// - `liquidity_amount` - The total amount of Liquidity the user desires to
///   withdraw.
/// - `token_min_a` - The minimum amount of tokenA the user is willing to
///   withdraw.
/// - `token_min_b` - The minimum amount of tokenB the user is willing to
///   withdraw.
///
/// #### Special Errors
/// - `LiquidityZero` - Provided liquidity amount is zero.
/// - `LiquidityTooHigh` - Provided liquidity exceeds u128::max.
/// - `TokenMinSubceeded` - The required token to perform this operation
///   subceeds the user defined amount.
