In stamnosslin/alexis106: Data from experiment on hearing ability in blind and sighted listeners

#' Data from experiment ALEXIS 106
#'
#' This is data from an experiment on basic auditory abilities in three groups of
#' listeners: (1) 26 blind, (2) 26 sighted and age-matched to the blind, and (3) 40
#' young sighted listeners. For each listener, four threshold estimates were derived, '
#' called th.1, ..., th.4 in the data set. For details, see vignette
#'
