Add Adafruit_CircuitPython_DHTlib to bundle

I think this should do it, but there seems to more changes than i expected. One of these days i will get the hang of GIT. The only real changes are to the .gitmodule file.

@tannewt can you take a look at this and let me know your comment. Adding Adafruit_CircuitPython_DHTlib to bundle

The second commit looks good! The extra stuff looks like you need to run git submodule update. After selecting a new branch, the submodules are not updated and need to updated separately. Ping me on discord if you need help git wrangling.

@tannewt I did the rebase and git push --force. That cleaned it up.

@tannewt i renamed and tested the build-bundles.py and resultant .mpy file.
