Enumerable properties are made non-enumerable

[MikeJerred]

Enumerable properties are made non-enumerable after deserialization.

import { deserializeError, serializeError } from 'serialize-error';

class MyError extends Error {
  constructor(public params: any) {
    super('test');
  }
}

const error = new MyError({ name: 'foo' });
const serialized = serializeError(error);
const deserialized = deserializeError(serialized) as MyError;

// properties of deserialized.params are non-enumerable
