Improve data extraction

[annajung]

Description

There is a limitation with GitHub API rate limit that makes data extraction hard for medium to large size projects.

The code currently handles API rate limits by waiting an hour (time required to reset) which does not scale.

Improve current implementation of data extraction to work around the API limit

Possible Solution

• Leverage GraphQL API to lower API calls

Steps to Reproduce

To reproduce the error, run the following with a medium to large size repo

python runDataExtraction.py <organization> <repo>
