qualtRics 3.2.0

• Changed how multiple choice questions are mapped to an R factor with the convert argument to fetch_survey(), to now excluding NA as a factor level (#315)

• Deprecated the save_dir and force_request arguments for fetch_survey(), so that survey response downloads are no longer cached; calls to fetch_survey() now always query the Qualtrics API (#317)

• Added new tmp_dir argument to fetch_survey() so users can specify where survey results are briefly stored on disk (#327)
