Fix modules to use teal_data instead of tdata

installation instructions:

staged.dependencies::dependency_table(

  ref = "refactor",

staged.dependencies::install_deps()

Steps:

1. Assign yourself by writing your name next to the module in "Progress list" below.
2. Open separate branch tm_module_of_your_choice@refactor.
3. Make changes relevant changes. See model example:

• fix asserts

# from
checkmate::assert_class(data, "tdata")
  
# to
checkmate::assert_class(data, "reactive")
checkmate::assert_class(isolate(data()), "teal_data")

• Fix call to merge_expression_module, data_extract_multiple_srv and merge_expression_srv by removing join_keys argument. I adjusted teal.transform functions to work with new data (reactive teal_data). Adjusted methods doesn't need join_keys object as join_keys are already in teal_data object.
• Fix merge call evaluation in the module. Object data inherits from qenv so we don't need to convert tdata -> qenv anymore. Beware, exact calls in your module might differ from the one below.

# from 
anl_merged_q <- reactive({	   
  req(anl_merged_input())
  teal.code::new_qenv(tdata2env(data), code = get_code_tdata(data)) %>% 
      teal.code::eval_code(as.expression(anl_merged_input()$expr))
})
# to
anl_merged_q <- reactive({
  req(anl_merged_input())
  data() %>%
    teal.code::eval_code(as.expression(anl_merged_input()$expr))
})

• there might be more calls to data. Please beware that now data is a reactive holding teal_data instead of tdata (list of reactives).
• example change in validation rules

iv$add_rule("variables", shinyvalidate::sv_in_set(
 # set = names(data[[dataname]]()), message_fmt = "Not all selected variables exist in the data" # old
 set = names(data()[[dataname]]), message_fmt = "Not all selected variables exist in the data" # new
))

4. Make PR to the @refactor branch with only one module changed. ONE PR, ONE MODULE. Include example app in the initial comment!
5. Add a link to the PR next to the "Progress list"

First package is refactored. Went pretty easy. There are some validate/req artifacts in some modules which appears for a fraction of seconds. We will take care of it later 💪
