Let's take advantage of that. In addition to saving some code, this also moves us to using ARRAY_SIZE() to specify how many regulators we have which is less error prone. NOTE: Though I haven't done the math, this is likely an overall savings in terms of "static const" data. We previously always allocated space for 8 supplies. Each of these supplies took up 36 bytes of data (32 for name, 4 for an int).
