     * Builds a staking transaction for TON Pool contract. It uses 2 pool solution, and picks the best pool

     * @param params.delegatorAddress - The delegator address
     * @param params.validatorAddressPair - The validator address pair to stake to
     * @param params.amount - The amount to stake, specified in `TON`
     * @param params.preferredStrategy - (Optional) The stake allocation strategy. Default is `balanced`.
     * * `balanced` - automatically balances the stake between the two pools based on the current pool balances and user stakes
     * * `split` - splits the stake evenly between the two pools
     * * `single` - stakes to a single pool
     * @param params.referrer - (Optional) The address of the referrer. This is used to track the origin of transactions,
     * providing insights into which sources or campaigns are driving activity. This can be useful for analytics and
     * optimizing user acquisition strategies
     * @param params.validUntil - (Optional) The Unix timestamp when the transaction expires
     *
     * @returns Returns a promise that resolves to a TON nominator pool staking transaction.
