[sdiy] Standard markings for modular I/O & CV versus Audio?

personally I find any color scheme beyond maybe separating inputs and
outputs not really useful in modular and especially in Eurorack.

one person's LFO is another one's kick bass oscillator and what comes
out of a clock divider might be a slow logic signal or a sub bass square
wave signal. CV is audio and audio is CV - embrace the wild west ;)
