Put the decoder in a some git repository and post the link in here. Currently we are lacking code reviewers, so it would also help if someone else could go and take a look at the code. Remember to also include relevant test data in the sigrok-dumps repo and regression tests in sigrok-test.
For the extracted data; I would just output the binary data in a such way that it ends up in pulseview decoder binary view (and can also be dumped with sigrok-cli) then you can use a audio software to play it or process it further.
