/**
Serialize an `Error` object into a plain object.

- Non-error values are passed through.
- Custom properties are preserved.
- Buffer properties are replaced with `[object Buffer]`.
- Circular references are handled.
- If the input object has a `.toJSON()` method, then it's called instead of serializing the object's properties.
- It's up to `.toJSON()` implementation to handle circular references and enumerability of the properties.

@example
```
import {serializeError} from 'serialize-error';

const error = new Error('🦄');

console.log(error);
//=> [Error: 🦄]

console.log(serializeError(error));
//=> {name: 'Error', message: '🦄', stack: 'Error: 🦄\n    at Object.<anonymous> …'}
```

@example
```
import {serializeError} from 'serialize-error';

class ErrorWithDate extends Error {
	constructor() {
		super();
		this.date = new Date();
	}
}

const error = new ErrorWithDate();

console.log(serializeError(error));
//=> {date: '1970-01-01T00:00:00.000Z', name, message, stack}
```

@example
```
import {serializeError} from 'serialize-error';

class ErrorWithToJSON extends Error {
	constructor() {
		super('🦄');
		this.date = new Date();
	}

	toJSON() {
