use shinymeta for code exports

[GregorDeCillia]

I recently took a closer look at the shinymeta package and it seems all code exports that are available in sdcMicro can be produced with that package. However, I think this should be done alongside a rigorous refatoring.

Possible steps

• [ ] migrate all app-related code to R/ to implement the app and all of its components as (internal) functions.
• [ ] Use techniques similar to golem::add_css_file() in order to include the contents of inst/shiny/sdcApp/www/
• [ ] Use metaReactive() for code export
• [ ] Create parametrized Rmd Reports in inst for the "Anonymization Report" and the Landing page of the app

I could also try to only add the code export via shinymeta and leave the other points open for another day. What are your thoughts on this @bernhard-da ?

Schedule

I would wait with the actual code-export refactoring until shinymeta becomes more stable. However, the other points on this list could be implemented sooner.

@GregorDeCillia sound interesting and please, have a go. but i think this is (very) low priority.
