enhancement: mock different values based on other fields

[arthurfiorette]

Sorry for opening another issue. But i need to generate a different values depending on another fields, example:

export class Example {
  @Mock()
  isActive: boolean;

  @Mock() // Should only be defined if isActive is false.
  deactivationReason?: string;
}

So, it would be cool if i could write something like that:

export class Example {
  @Mock()
  isActive: boolean;

  @Mock((faker, self) => self.isActive ? null : faker.someMethod())
  deactivationReason?: string;
}

Where data is what is already generated, like isActive (Probably depends on execution / field order) because it was declared first.

Also, if it is possible, you also could add the hability to return promises.

Thanks for making this amazing library!

Also, if i use null or undefined as the @Mock(() => result), it throws:

    TypeError: Cannot convert undefined or null to object

Can you open a new issue with the full steps to reproduce?
