/// Initialize reward for a Whirlpool. A pool can only support up to a set
/// number of rewards. ### Authority
/// - "reward_authority" - assigned authority by the reward_super_authority for
///   the specified
///
/// reward-index in this Whirlpool
/// ### Parameters
/// - `reward_index` - The reward index that we'd like to initialize. (0 <=
///   index <= NUM_REWARDS)
///
/// #### Special Errors
/// - `InvalidRewardIndex` - If the provided reward index doesn't match the
///   lowest uninitialized
///
/// index in this pool, or exceeds NUM_REWARDS, or
/// all reward slots for this pool has been initialized.
