/**
 * Compiles a templated response with slot values from the
 * provided slot map.
 *
 * For example, when passed "What date do you want your ${flowers}?"
 * and the slot map contains a slot with name `flowers` it will replace
 * it with the value.
 *
 * It will handle the different potential value types for slots such as
 * strings, numbers, dates and durations.
 *
 * By default, if the slot value does not exist, the template value is left untouched.
 *
 * @param responseOutput
 * @param slots
 * @param replaceWhenUndefined - When set to true, it will replace the value with 'undefined' if it doesn't exist, default behavior is to leave the template as is.
