[PD] parametric equalizer

Not a ready made multi band equalizer, but the 'else' library also has a
biquad coefficient generator, which offers more options than the ggee
library (see else/bicoeff). Else also has ready made filters that don't
require biquad~ and take audio signals to control all the parameters (ie.
[else/eq~], [else/lowshelf~], [else/highshelf~], etc).
I thought about making a ready made parametric in else, but you can easily
build it your own. For the lowest and highest band you need to use
lowshelf and highshelf respectively. Then use "eq~" for the mid bands.
cheers
