bcmaps 2.2.1

• In the cded_() functions, the ask argument, which controls if the user is
  asked to store data in the cache, was ignored. It is now respected (#147).
• utm_convert() now respects tibble classes
  (#143, #148).
• Fixed a bug in utm_convert() where new coordinates could be mismatched with
  the wrong rows from the input data frame.
