 * Save/Load face
 *
 * This allows you to save your settings (including location, birthday, etc) to
 * LFS, which is not wiped when firmware is updated, and then load them again.
 * It provides multiple save slots (four by default).
 *
 * Press ALARM to cycle through save slots. Long press LIGHT to save to the
 * current slot. Long press ALARM to load from the current slot. The date that
 * a save was taken is shown in YYMMDD format , or "no dat" if the slot is
 * empty. The index of the current slot is displayed in the upper right corner.
 *
 * While the time that a save was taken is recorded, it is not currently
 * restored.
