Adding loader for CompMusic Raga Dataset

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 (ongoing, it takes a while)

At the moment there is no Zenodo entry for this dataset. We will create it soon, separating the audio (which must be restricted) and the annotations/features (which are open).

@genisplaja small request: can you change the name of the module from compumusic_raga_dataset to simply compmusic_raga? it will make our lives easier in the tables and for the user if the name is shorter

@magdalenafuentes done:) The part _dataset definitely not needed here!
