Expose Sorting Function

[FlorianWendelborn]

In the case I’m currently working on, I don’t know (and have no easy way to retrieve) all CSV headers in advance. It’d be great if this library would expose an overridable def sort_headers method.

or simply choose whether to sort the headers or not. For me it seems weird that you want alphabetically ordered fields, but it's fair if some people want that - but why not make it based on the serializer as the rest of DRF does? so if you want them alphabetical order, then you simply order them alphabetically in the serializer.

It's really difficult to change the fields in the viewset currently. Currently i am doing:

def get_renderer_context(self):
        context = super().get_renderer_context()
        # force the order from the serializer.
        context['header'] = self.serializer_class.Meta.fields
        return context

But that is really hacky (and seems weird that i have to force it to do the 'default'. Also this was problematic (the code above) when i went to change fields dynamically in the serializer making the seperation of responsibilities really difficult.

TL;DR Please just remove the ordering and/or make a function where you can PICK to choose to sort them alphabetically. I can make a PR if neeeded be that fixes this, but i would prefer that it is merged if i spend time creating it.
