3.0.0 - getDescriptionStatsBy update & more

• BREAKING: The input parameters have changed for getDescriptionStatsBy and dropped old deprecated parameter conversion:

• show_missing_digits -> show_missing.digits
• show_missing -> useNA
• sig.limit -> statistics.sig_lim
• two_dec.limit -> statistics.two_dec_lim

• Fixed bug in getDescriptionStatsBy when providing a character input
• Made getDescriptionStatsBy S3 aware with tidyselect pattern for generating tables.
• The yamlDump can now take a character string and assume that is a json that needs conversion
• Added set_column_labels and set_column_units for using dplyr syntax for Hmisc::label and Hmisc::units operations.
• The units column in getDescrptionStatsBy can now have a custom name (also changed default name to "Units")
• Changed addBoxClr to addBoxStyle for Transition-class (minor breaking change)
