workflowsets 1.1.0

• Ellipses (...) are now used consistently in the package to require optional arguments to be named; collect_metrics() and collect_predictions() are the only functions that received changes (#151, tidymodels/tune#863).
• Enabled evaluating censored regression models (#139, #144). The placement of
  the new eval_time argument to rank_results() breaks passing-by-position
  for the select_best argument.
• Added a collect_notes() method for workflow sets (#135).
• Added methods to improve error messages when workflow sets are mistakenly
  passed to unsupported functions like fit() and predict() (#137).
• Added a new argument, type, to the workflow_set autoplot() method. The
  default, "class", retains the existing behavior of mapping model type to
  color and preprocessor type to shape, while the new "wflow_id"
  type maps the workflow IDs to color (#134).
• Added type checking for inputted arguments (#136, #131).
