Adds a catch24 option to compute Mean (DN_Mean) and Standard Deviation (DN_Spread_Std) as features in addition to the standard catch22. Deletes R wrapper from repository as native R implementation Rcatch22 is on CRAN and requires no manual compilation. Interpolates the CO_f1ecac feature to now return a double instead of an integer for more nuanced performance in feature-based time-series analysis applications, such as time-series classification.
