+Subject: [PATCH 2/2] configure hook state machine timing
+
+introduce a bunch of new config options to configure hook state
+machine timing parameters:
+ * digit_low_time_min
+ * digit_low_time_max
+ * digit_high_time_min
+ * digit_high_time_max
+ * flash_time_min
+ * flash_time_max
+ * hook_off_time
+ * hook_on_time
+
