processChoiceData: Process Choice Data
In jdtrat/iapsr: IAPS Analysis Functions

This function takes the data column from the output of readChoices and runs four functions, binding the results in a dataframe for easy manipulation:

getPhases which separates the three phases of the task, saving them to the environment phrase, which is initialized behind the scenes.
getIcons which gets the icon information shown to the subject per round.
getChoices which gets the choice the subject makes.
getImageShown which gets the images the subject is shown after choosing an icon.
