hi 👋  
i was thinking maybe we could add validation for max and min size of user uploaded files in `django.forms.fields.FileField`

i think i can implement this myself, if accepted

is this something you would want to see in django?

Yes, I’d like to see max file size at least. This could be through a field parameter (most convenient) or a validator (more flexible).

Looking around the docs, I couldn’t find any advice on setting a maximum file size, which I think is a bit odd!
