geckor 0.2.0

Major changes

• Significant speed-up (at least 3x) of the coin_history() and coin_history_range() functions.
• All of the coin_history_* functions have been re-written so that they can retrieve data for multiple coins (up to 30) in one call.
• The internal api_request() function has been modified to fail more gracefully when the API calls time out or errors occur.

Minor changes

• Modified vignettes to reflect major changes in the package.
• Modified vignettes to avoid hard failures during their build (caused by going over the API rate limit).
• Minor improvements and edits in the package documentation.
