Added LANA TNY board #164

The LANA TNY is a development board by Phyx based on the CH32V203G6U6.
It is sold through the official Adafruit store: here
It is comparable to the already added Adafruit QT Py CH32V203 (in pull request #136) but has some extra GPIO pins exposed and some slightly different pin arrangement.
