Change modules to use data argument instead of datasets

[gogonzo]

Followup to:

• Pass the list of reactive data to the module. teal#654
• data_merge - remove dependency on FilteredData and chunks. teal.transform#61
• data_extract - remove dependency on datasets teal.transform#67

Required fixes:

• Remove datasets argument and introduce data argument.
• Use new data_extract and data_merge

NOTE: teal.modules.hermes using datasets$get_data(filtered = TRUE) and datasets$get_data(filtered = FALSE). We need to resolve this situation.

@gogonzo does this need to be fixed for this release? or later?

@danielinteractive not this sprint - next increment. Currently it's in sprint 59. We will decide during PI planning if we are able to address this
