Adding the latest version of compmusic_otmm_makam

[sertansenturk]

Hello mirdata people!

As we discussed aeons ago, compmusic_otmm_makam has a fix version that was not available when @genisplaja was implementing the original loader.

It was added to Zenodo (link) later, and it would be nice to have the latest version available in mirdata. I believe it is a small task, and I am happy to make the change myself.

To the best of my understanding, all I need to do is to follow the guideline in contributing.html#datasets-with-multiple-versions:

• [ ] Add dlfm2016-fix1 to INDEX
• [ ] Point default to the fix version

As the acceptance criteria, I could:

• Add/update the unittests
• Run (ad-hoc?) integration tests ensuring either version is downloaded appropriately.

Please let me know your thoughts, if I need to show extra care on some bits & bobs, and please do not hesitate to point out any concerns.

P.S: pinging @nkundiushuti, @genisplaja, @rabitt for visibility
