CRAN v0.1.4

Minor patch to resolve upstream check issues introduced by dplyr v1.0.0 and
tsibble v0.9.0.

New features

• Circular time plots are now supported by setting polar = TRUE in
  gg_season().

Improvements

• Added partial matching of the type argument in ACF().
• Updated feat_spectral() to use stats::spec.ar() instead of
  ForeCA::spectral_entropy(). Note that the feature value will be slightly
  different due to use of a different spectral estimator, and the fix of a
  bug in ForeCA.

Bug fixes

• Fixed the minimum data length for seasonal estimation in feat_stl().
