23	* Initializes a new instance of the {@link BaseStripeClient} class.
24	*
25	* The constructor takes a single argument. The argument can be a string, in which case it
26	* should be the API key. It can also be an array with various configuration settings.
27	*
28	* Configuration settings include the following options:
29	*
30	* - api_key (null\|string): the Stripe API key, to be used in regular API requests.
31	* - client_id (null\|string): the Stripe client ID, to be used in OAuth requests.
32	* - stripe_account (null\|string): a Stripe account ID. If set, all requests sent by the client
33	* will automatically use the {@code Stripe-Account} header with that account ID.
34	* - stripe_version (null\|string): a Stripe API verion. If set, all requests sent by the client
35	* will include the {@code Stripe-Version} header with that API version.
36	*
37	* The following configuration settings are also available, though setting these should rarely be necessary
38	* (only useful if you want to send requests to a mock server like stripe-mock):
39	*
40	* - api_base (string): the base URL for regular API requests. Defaults to
41	* {@link DEFAULT_API_BASE}.
42	* - connect_base (string): the base URL for OAuth requests. Defaults to
43	* {@link DEFAULT_CONNECT_BASE}.
44	* - files_base (string): the base URL for file creation requests. Defaults to
45	* {@link DEFAULT_FILES_BASE}.
46	*
47	* @param array<string, mixed>\|string $config the API key as a string, or an array containing
48	* the client configuration settings
