 - Fix documentation related to CRAN submission.
 - Fix some errors from passing "" as a key.
 - `pvt_twitter` and `pub_wiki` now use `time_type` and `time_values` args instead of mutually exclusive `dates` and `epiweeks` (#236). This matches the interface of the `pub_covidcast` endpoint.
+- All endpoints now support the use of "\*" as a wildcard to fetch all dates or epiweeks (#234).
