Add RadiusNeighborsClassifier

[sanketsarang]

Add RadiusNeighborsClassifier model into the library.

Primary File to Change: https://github.com/blobcity/autoai/blob/main/blobcity/config/classifier_config.py

Reference RadiusNeighborsClassifier Implementation:
https://github.com/blobcity/ai-seed/blob/main/Classification/Radius%20Neighbors/RadiusNeighborsClassifier.ipynb

Dependencies if any, must be appropriately added. Test run of the train function on a classification problem must pass, and the function must attempt to train a RadiusNeighborsClassifier as a potential best fit model.

Can I work on this issue?

[sanketsarang]

Done, it's assigned to you @aadityasinha-dotcom

[aadityasinha-dotcom]

We have to directly add the model and its Tuning parameters just like KNeighborsClassifiers right?

[sanketsarang]

Yes, that is correct. Just make sure you do a test run using a Classification dataset before the PR.
