Implement a shiny module exporting a Report

[kpagacz]

linked to insightsengineering/NEST-roadmap#11

The prototype of the UI is included here: https://balsamiq.cloud/st5j94y/pkhl0a6/r80A7

Recommendation, the order is important:

implement the Export as... module which can be embedded (the previewer module and Download Report button)

Download Report button

The previewer module

implement a small module that embeds the module exporting the report as a modal window opened after clicking a Download Report button (so this module is this small button and the logic to pop up the modal with the module implemented in the first point)

These modules will take Report as an argument (which contains a vector of Cards), and use Renderer to render the report and then allow users to download it (zip file with all needed files).

We need the second module to embed it in teal modules. The first one will be part of the previewer module.

The UI part is located in the (each teal module UI)/(or one global), and have to be conditional. So if we are not using the Reporter the UI should not be included. Global button module seems to be a better choice?
