• 3 shiny Modules added: downlaod_reporter_button_srv, add_card_button_srv and simple_reporter_srv (combine two previous ones).
• Full coverage of code in tests.

Possible controversial point is that in the shiny apps we will recommend, such code:

  card_r <- eventReactive(
    teal.reporter::extract_addcard_input(input), {

teal.reporter::extract_addcard_input is looking for an id with a suffix "addReportCardButton$". So there is very very small probability of id collision. I prefer to have it readable as sb might want to use it directly, without usage of teal.reporter::extract_addcard_id. teal.reporter::extract_addcard_input(input) requires an active reactive context, and eventExpr argument is such.

Fo the previewer task we need another download module as we need a custom UI and does not need a modal. Most of the code from downlaod_reporter_button_* module could be reused.
I expected some small updates when introducing for TEAL.
