What's the role of the date_range parameter in the robyn_allocator() function?

Hi @gufengzhou !

Thanks for sharing your knowledge with us in the Robyn Bootcamp at the NYC office. I am following up on this question that I asked during our Q & A in the bootcamp.

You told us that the date_range parameter decides what ad-stock data the allocator will consider. But for the average spend, I remember you telling that if we leave this NULL, it considers the whole modeling window to arrive at the averages. Does this also mean that when instead of leaving it NULL, if we do provide the date_range let's say c(2023-10-01,2023-10-31), it will consider only this month of October 2023 to derive the average spend levels?
