    Configure a new `got` instance with default `options`.
    The `options` are merged with the parent instance's `defaults.options` using `got.mergeOptions`.
    You can access the resolved options with the `.defaults` property on the instance.

Additionally, `got.extend()` accepts two properties from the `defaults` object: `mutableDefaults` and `handlers`.

It is also possible to merges many instances into a single one:
    - options are merged using `got.mergeOptions()` (including hooks),
    - handlers are stored in an array (you can access them through `instance.defaults.handlers`).

@example
    ```js
    const client = got.extend({
        prefixUrl: 'https://example.com',
        headers: {
            'x-unicorn': 'rainbow'

client.get('demo');

// HTTP Request =>
    // GET /demo HTTP/1.1

    // x-unicorn: rainbow

    Extends parent options.
    Avoid using [object spread](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax#Spread_in_object_literals) as it doesn't work recursively.

Options are deeply merged to a new object. The value of each key is determined as follows:

- If the new property is not defined, the old value is used.
    - If the new property is explicitly set to `undefined`:
        - If the parent property is a plain `object`, the parent value is deeply cloned.
        - Otherwise, `undefined` is used.
    - If the parent value is an instance of `URLSearchParams`:
        - If the new value is a `string`, an `object` or an instance of `URLSearchParams`, a new `URLSearchParams` instance is created.
            The values are merged using [`urlSearchParams.append(key, value)`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams/append).
            The keys defined in the new value override the keys defined in the parent value.
        - Otherwise, the only available value is `undefined`.
    - If the new property is a plain `object`:
        - If the parent property is a plain `object` too, both values are merged recursively into a new `object`.
        - Otherwise, only the new value is deeply cloned.
    - If the new property is an `Array`, it overwrites the old one with a deep clone of the new property.
    - Properties that are not enumerable, such as `context`, `body`, `json`, and `form`, will not be merged.
    - Otherwise, the new value is assigned to the key.

**Note:** Only Got options are merged! Custom user options should be defined via [`options.context`](#context).

@example
    ```
    const a = {headers: {cat: 'meow', wolf: ['bark', 'wrrr']}};
    const b = {headers: {cow: 'moo', wolf: ['auuu']}};

{...a, ...b}            // => {headers: {cow: 'moo', wolf: ['auuu']}}
    got.mergeOptions(a, b)  // => {headers: {cat: 'meow', cow: 'moo', wolf: ['auuu']}}
    ```
