/**
 * The poll function implements a retry mechanism for asynchronous operations.
 * It repeatedly calls the callback function to fetch data and then uses the
 * verify function to check if the retrieved data meets the desired criteria.
 *
 * @param   callback  A callback function that is responsible for fetching or retrieving data. It should be an asynchronous function that returns a Promise.
 * @param   verify    A callback function that determines if the retrieved data meets the desired criteria. It should accept the data returned by callback and return a boolean value (true if the data is valid, false otherwise).
 * @param   retries   (optional): An integer specifying the maximum number of times the function will attempt to poll before giving up. Defaults to 100.
 * @returns A Promise that resolves to the data retrieved by callback when the verify function returns true, or rejects with an error if the maximum number of retries is reached.
