Joyn 0.2.2

• Remove unmasking functions as we realized that they are not necessary.

joyn 0.2.1 (Not in CRAN)

• Add anti_join() function.

• Add unmask_joyn() function to unmask joyn functions that mask dplyr equivalents.

• Add information about duplicated obs in by variable when match type is 1 rathern than m.

• improve inefficiencies in deep copies with m:m joins

• Replace m:m joins from data.table::merge.data.table to collapse::join. Thanks to @SebKrantz for the suggestion (Just a question regarding usage of collapse::join #58).

• Add information about duplicated obs in by variable when match type is 1 rather than m.

• Internal: improve storing of joyn messages.

• Improve creation of reporting variable. Now, it is created in [collapse::join] rather than in joyn function. In addition, the reporting variable is created as factor to improve performance. Thanks to @SebKrantz for the suggestion (Just a question regarding usage of collapse::join #58)

breaking changes

• Now, by default, joyn will not sort the data. This is to avoid unnecessary
  computational time that most of the time is not needed.
  If the user wants to sort the data, they can use the sort argument, which triggers
  the sorting mechanism of collapse package.

• report variable (named ".join" by default) is now a factor instead of character. Yet, users can still use character if they want with the reporttype = "character".
