Anduril: implement quick aux LED on/low switching, see description at the top

721-8C_turn_aux_off_low.diff

######################################################################################################################################
# 721-8C_turn_aux_off_low.diff: implements @Light_Veteran feature request[1], to wit:
#	8C will turn the aux LED on (on low) if it’s off, and the same 8C will turn it off if it’s on (whether in low, high or blink).
# [1] per https://budgetlightforum.com/t/anduril-2-feature-change-suggestions/218045/147
#
# Apply it with `patch -p1 <721-8C_turn_aux_off_low.diff` at the same directory you expanded 721.tgz,
# 	or `patch -p2 <721-8C_turn_aux_off_low.diff` into the same (or other release, but then no guarantees)
