[Feature]: Download Archived Item button

[Shrinks99]

Context

Archived items can be composed of an arbitrary number of WACZ files. For larger crawls, there can be a lot of these!

Now that collections can be downloaded as a single WACZ by streaming the data into a single ZIP file download, we should do the same for single archived items!

What change would you like to see?

As a user, I want to be able to download my whole archived item with one click. I don't want to worry about having to set up a replay.json file to view my archived item locally. I just want it to work!

Requirements

1. Users can download the entire archived item through an action in the actions menu
2. Users can download the entire archived item through a button on the files page.
