CV out reversed

[hwkcgn]

as described in https://forum.zrna.org/t/5v-cv-will-akso-be-good-in-modular-setups/103/43 CV output thru trs-config is reversed to what one would expect from the representation in the patcher: e.g. CV set to -5 - +5V: -64 -> +5V, +64 -> -5V and CV set to 10V: -64 -> +10V, +64 -> 0V.
