Add MMTF->JSON dumping facility to integration tests.
If there's integration test changes to mmtf output, it's somewhat hard to debug. So - taking a cue from the SQLite tests - I'm adding a small utility script which can dump MMTF data into a JSON format.
This requires the Python version of the MMTF reader to be installed to properly function, though there's a fall-back if it isn't. (We just don't dump the plaintext version.)
