Feature Request: Make dict a option instead of a list in MultiTableMixin

[Frodothedwarf]

I've used this project for a good while now, and the SingleTableMixin are working great, but I'm at a place where I need to use multiple tables on one view.

I figured it must be at least as useful, but I've figured it's a lot harder to do so.
By making a dict option instead of a list option only, you can easily reference the tables at the places they go.

In the current flow you need to do it like this:

class DetailView(PermissionRequiredMixin, MultiTableMixin, DetailView):
    permission_required = ["permission"]
    model = Model
    template_name = "template.html"
    tables = [
        ModelTable
    ]

    def get_tables_data(self):
        return [
            self.object
        ]

And then in the template you have to loop through the list like this:

{% for table in tables %}
    {% if table.prefix == "model_table" %}
        {% render_table table %}
    {% endif %}
{% endfor %}

I want to eliminate the need for looping through the tables to find the correct one, and I would hope that a option would be something like:

class DetailView(PermissionRequiredMixin, MultiTableMixin, DetailView):
    permission_required = ["permission"]
    model = Model
    template_name = "template.html"
    tables = {"model_table": ModelTable}

    def get_tables_data(self):
        return {
            "model_table": self.object
        }

With a template that looks like:
{% render_table_dict "model_table" %}

I can make the commits, but first wanted to know if it's something of interest for the project as a whole? I at least would think that alot of people would benefit from a change like this.
