Update django-floppyforms to 1.6.2

[pyup-bot]

There's a new version of django-floppyforms available.
You are currently using 1.6.0. I have updated it to 1.6.2

Changelog

1.6.2

* `169`_: Use the attributes ``ClearableFileInput.initial_text``,
 ``ClearableFileInput.input_text``,
 ``ClearableFileInput.clear_checkbox_label`` to determine the used text in the
 template. This was inconsistent so far with Django's behaviour.

### 1.6.1

• 167_: Fix django-floppyforms' CheckboxInput.value_from_datadict which
  was inconsistent with Django's behaviour.
