Adding loader for CompMusic Carnatic Varnam

This one has been pending for so long, so it's nice that we got it finally here!

Description

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

• [x] Describe annotations included in the dataset
• [x] Indicate the size of the datasets (e.g. number files and duration, hours)
• [x] Mention the origin of the dataset (e.g. creator, institution)
• [x] Describe the type of music included in the dataset
• [x] Indicate any relevant papers related to the dataset

Dataset loaders checklist:

• [x] Create a script in scripts/, e.g. make_my_dataset_index.py, which generates an index file.
• [x] Run the script on the canonical version of the dataset and save the index in mirdata/indexes/ e.g. my_dataset_index.json. This is done but we will have to re-run it when we have the new canonical (and fixed) version of the dataset.
• [x] Add new version in the index, remotes, docs.
• [x] Create a module in mirdata, e.g. mirdata/my_dataset.py
• [x] Create tests for your loader in tests/datasets/, e.g. test_my_dataset.py
• [x] Add your module to docs/source/mirdata.rst and docs/source/table.rst
• [x] Update REMOTES
• [x] Run tests/test_full_dataset.py on your dataset.

Loader made possible thanks to @adithishankar19's help :)
