* Note: for cURL, a minimum of 1 second applies, as DNS resolution

* (string, default: php-requests/$version)
* - `follow_redirects`: Should we follow 3xx redirects?
* (boolean, default: true)
* - `redirects`: How many times should we redirect before erroring?
* (integer, default: 10)
* - `blocking`: Should we block processing on this request?
* (boolean, default: true)
* - `filename`: File to stream the body to instead.
* (string|boolean, default: false)

* for Basic authentication
* (\WpOrg\Requests\Auth|array|boolean, default: false)
* - `proxy`: Proxy details to use for proxy by-passing and authentication

* - `hooks`: Hooks handler.
* (\WpOrg\Requests\HookManager, default: new WpOrg\Requests\Hooks())
* - `verify`: Should we verify SSL certificates? Allows passing in a custom

*
* - `url`: Request URL Same as the `$url` parameter to
* {@see \WpOrg\Requests\Requests::request()}
* (string, required)
* - `headers`: Associative array of header fields. Same as the `$headers`

* - `type`: HTTP request type (use \WpOrg\Requests\Requests constants). Same as the `$type`

* (string, default: `\WpOrg\Requests\Requests::GET`)
* - `cookies`: Associative array of cookie name to value, or cookie jar.
* (array|\WpOrg\Requests\Cookie\Jar)
*
* If the `$options` parameter is specified, individual requests will
* inherit options from it. This can be used to use a single hooking system,
* or set all the types to `\WpOrg\Requests\Requests::POST`, for example.
*
* In addition, the `$options` parameter takes the following global options:
*
* - `complete`: A callback for when a request is complete. Takes two
* parameters, a \WpOrg\Requests\Response/\WpOrg\Requests\Exception reference, and the
* ID from the request array (Note: this can also be overridden on a
