This adds a feature to etable that automatically renames categorical variables in regression tables. The user can specify a formatting template (default is "{variable}={value}"). It should work either for pandas categoricals (i.e "y ~ x + c" when c is categorical) and with categorical variables generated in the regression formula with the C() or i() operator.
To do this, the existing rename_categoricals function is slightly extended to allow using formatting templates.
