Renders a file input.
This method will generate the `name` and `value` tag attributes automatically for the model attribute
unless they are explicitly specified in `$options`.
@param array $options the tag options in terms of name-value pairs. These will be rendered as
the attributes of the resulting tag. The values will be HTML-encoded using [[Html::encode()]].

If you set a custom `id` for the input element, you may need to adjust the [[$selectors]] accordingly.

@return $this the field object itself.
