/**
 * `TestNetDispenserApiClient` is a class that provides methods to interact with the [Algorand TestNet Dispenser API](https://github.com/algorandfoundation/algokit/blob/main/docs/testnet_api.md).
 * It allows you to fund an address with Algo, refund a transaction, and get the funding limit for the Algo asset.
 *
 * The class requires an authentication token and a request timeout to be initialized. The authentication token can be provided
 * either directly as a parameter or through an `ALGOKIT_DISPENSER_ACCESS_TOKEN` environment variable. If neither is provided, an error is thrown.
 *
 * The request timeout can be provided as a parameter. If not provided, a default value is used.
 *
 * @property {string} authToken - The authentication token used for API requests.
 * @property {number} requestTimeout - The timeout for API requests, in seconds.
 *
 * @method fund - Sends a funding request to the dispenser API to fund the specified address with the given amount of Algo.
 * @method refund - Sends a refund request to the dispenser API for the specified refundTxnId.
 * @method limit - Sends a request to the dispenser API to get the funding limit for the Algo asset.
 *
 * @example
 * ```typescript
 * const client = new TestNetDispenserApiClient({ authToken: 'your_auth_token', requestTimeout: 30 });
 * const fundResponse = await client.fund('your_address', 100);
 * const limitResponse = await client.getLimit();
 * await client.refund('your_transaction_id');
 * ```
 *
 * @throws {Error} If neither the environment variable 'ALGOKIT_DISPENSER_ACCESS_TOKEN' nor the authToken parameter were provided.
