/**
 * We try to estimate the maximum possible gas that the transaction will consume
 * without requiring the signature of the user. The idea is to apply 2 different strategies
 * according to the type of request:
 * - deploy: the server signs the request and estimates the gas of the deployment with a static call
 * - relay: we split the requests into different stages
 *    - preEnvelopedTxEstimation: the gas required without the payment and the internal call
 *    - paymentEstimation: the gas required for the payment
 *    - internalEstimation: the gas required for the internal call
 *    - POST_DEPLOY_NO_EXECUTION: when there is no execution in deployment, an additional 4_000 are needed
 *    - POST_DEPLOY_EXECUTION: when there is execution in deployment, an additional 1_500 are needed
 *    - STORAGE_REFUND: After the nonces were already touched by a smart wallet deployment or smart wallet execution, we need to subtract 15_000
 * - Manually subtract:
 *    - Without signature, we cannot analyze if some of the gas costs should be included or not, to avoid underestimating the relay transaction
 *      the costs are included in all of them. These costs can be subtract by using the following constants:
 *      - POST_RELAY_DEPLOY_GAS_COST: The transfer back cost is always included since we cannot know if the smart wallet is going
 *        to have some balance after the execution
 *      - ACCOUNT_ALREADY_CREATED: The owner address of the smart wallet was previously created. A utility function was included to check
 *        if the owner address of smart wallet was already created
 * @param relayRequest
 * @param signer
 * @param options
 * @returns
