### Major changes

1. Updated sankey_list_maker to tweak the following arguments:
• weight is a T/F value that indicates whether you want the Sankey weighted or not.
• censor_vars takes a vector of variables to use for censoring. If named will create states with those names. Default is NULL.
• absorbing_var takes a vector of variables that will be used for “absorbing” states. Required to be named. Default is NULL. Replaces requirement of having a “death” variable in the cohort.
2. Updated sunburst_maker and sankey_list_maker to tweak the following arguments:
• gofl_formula replaces strat_vars and filt_vars. Now you can just enter your own gofl formula for how you want the Sankey filtered.

### Minor changes

1. Fixed bug that kept in None state label when not present.
2. Fixed bug (mentioned above) that forced users to have a death_date variable.
3. If variables to be used in the filtering and stratification are stype vectors package will convert to base types.
4. gofl_formula can use v_nominal, character, or nominal variables. If using a character and there are > 10 unique values, will throw error and force user to convert to nominal.
5. Always calculates pathways if unweighted (even if there are a lot of states/stages) but throws warning.
