Adding loader for BAF

Please use the following title: "Adding loader for MyDATASET". If your pull request is work in progress, change your title to "[WIP] Adding loader for MyDATASET" to avoid reviews while the loader is not ready.

Description

Please include the following information at the top level docstring for the dataset's module mydataset.py:

• Describe annotations included in the dataset
• Indicate the size of the datasets (e.g. number files and duration, hours)
• Mention the origin of the dataset (e.g. creator, institution)
• Describe the type of music included in the dataset
• Indicate any relevant papers related to the dataset
• Include a description about how the data can be accessed and the license it uses (if applicable)

Dataset loaders checklist:

• Create a script in scripts/, e.g. make_my_dataset_index.py, which generates an index file.
• Run the script on the canonical version of the dataset and save the index in mirdata/indexes/ e.g. my_dataset_index.json.
• Create a module in mirdata, e.g. mirdata/my_dataset.py
• Create tests for your loader in tests/datasets/, e.g. test_my_dataset.py
• Add your module to docs/source/mirdata.rst and docs/source/table.rst
• Run tests/test_full_dataset.py on your dataset.

If your dataset is not fully downloadable there are two extra steps you should follow:

• Contacting the mirdata organizers by opening an issue or PR so we can discuss how to proceed with the closed dataset.
• Show that the version used to create the checksum is the "canonical" one, either by getting the version from the dataset creator, or by verifying equivalence with several other copies of the dataset.
• Make sure someone has run pytest -s tests/test_full_dataset.py --local --dataset my_dataset once on your dataset locally and confirmed it passes

Please-do-not-edit flag

To reduce friction, we will make commits on top of contributor's pull requests by default unless they use the please-do-not-edit flag. If you don't want this to happen don't forget to add the flag when you start your pull request.

Hey @guillemcortes, I am just leaving a few tiny comments but the loader looks really nice. Good coverage, docs rendering correctly, and tests passing :) I'll invite @nkundiushuti, @magdalenafuentes, and @harshpalan to take a look, and IMO we can merge!

[guillemcortes]

Hi @genisplaja, thanka for your comments, I've done the according modifications. I've also improved the csv2pandas management and atomized the function. I think now it's better. I've also included the corresponding test. Would you mind checking it? Thanks!

[genisplaja]

That's nice! That is ready to go in my opinion. Thanks @guillemcortes :) Maybe @harshpalan or @magdalenafuentes could take a look? 🙏🏼🙏🏼🙏🏼

Hi, @guillemcortes @genisplaja sorry for the delayed response. This looks good. I'm approving the changes, please go ahead and merge it. Thanks.
