DecodingKeys is not preserved in spruce tck file with new Moore version
Generating spruce dst and tck file with this script, I found DaVinci can't find the DecodingKeys. And that only happens with newer version of Moore (I tried v55r16), however, with Moore v55r11, the Decodingkeys can be found in tck file, as shown in the attached tck files.
