Fix CD4053 pinout (14/15 swapped)

KiCad Bot requested to merge github/fork/dlharmon/cd4053fix into master

Created by: dlharmon

Data sheet as linked in the part http://www.ti.com/lit/ds/symlink/cd4052b.pdf

Part with same pinout and clearer data sheet: https://assets.nexperia.com/documents/data-sheet/74HC_HCT4053.pdf

Before

Pins 14 and 15 are swapped. Screenshot from 2019-12-11 11-47-57

After

Swapped pins 14, 15 to match data sheet Renamed channels from X,Y,Z to A,B,C as in the data sheet The datasheet's "ax OR ay" is shortened to just "A" I left the right side pins "A0 and A1" rather than the datasheet's "AX" and "AY" as I felt it was clearer how it operates that way.
