add kinesis/kint32

[bytetinkerer]

Added support for Teensy 3.2 to the kinx/kint board for Kinesis keyboards.

Description

I added a new keyboard by copy-pasting from kinesis/kint36 and adding the necessary modifications for the Teensy 3.2.

I tested it with a Kinesis Advantage (KB500) with the kinT keyboard controller board (v2020-06-30) and a Teensy 3.2. It works!
