healthyR.ts 0.2.2

Breaking Changes

1. Fix 345 - Fix ts_sma_plot() There is a change in the API of this function.
   It now requires a data.frame/tibble to be passed to the .data parameter, and
   it also now requires the input of a date column and value column. This also now
   no longer returns invisible. There was also a fix in the sliding calculation
   to appropriately use the given value column.

New Features

1. Fix #342 - Add function ts_extract_auto_fitted_workflow() Which will pull
   out the fitted workflow from any of the Boilerplate functions.

Minor Fixes and Improvements

1. Fix #343 - Add attributes to output list of boilerplate functions.
2. Fix #347 - Fix ts_auto_lm() by dropping step_rm() and step_corr() which
   would prevent calibrate_and_plot() from working due to modeltime_calibration()
   failing. Also dropped unused parameters from function and documentation.
3. Fix #349 - Fix to ts_lag_correlation() select statement.
