Adding loader for DCASE'23 Task 6A/6B

[tanmayy24]

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 total duration of the dataset in hours, and (optionally) also list the number of individual files
• Mention the origin of the dataset (e.g. creator, institution)
• Describe the type of audio 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 soundata/indexes/ e.g. my_dataset_index.json.
• Create a module in soundata, e.g. soundata/my_dataset.py.
• Create tests for your loader in tests/, e.g. test_my_dataset.py.
• Add your module to docs/source/soundata.rst and docs/source/quick_reference.rst.
• Run black, flake8 and mypy (see Running your tests locally).
• Run tests/test_full_dataset.py on your dataset.
• Check that codecov coverage does not decrease.

Looks good, also the new download and extract 7z files functions. Dataloader docstring needs revision since it is not rendering properly.
