Provide convenient sample data in a package, such as sample data CHrX in sample scripts

[tongtongy666]

Hello, it's a great honor to communicate with you. In the process of using Pixy, it is very difficult for me to find the data in the sample script you provided, which involves downloading the data from another article or database, and it is not convenient for people who use this tool for the first time to understand the data form. So I suggest that you can directly add sample data in github, so that learners can more easily understand the specific forms of data available. Thank you very much.
