Preserve Links and Text related to Public Dataset

[Precious-Macaulay]

See #51

I updated the text_extraction.xml stylesheet to keep external links without affecting readability and also searched for more articles to know where public datasets text tends to be and updated the stylesheet to handle that accordindly. i have attached a copy of my extracted text data from some articles i gathered including the example in the issue too.
text.csv

Alright

I just reviewed and tested this PR on a couple PMCids. Here are the output files
17048730_text.csv
17048739_text.csv

These outputs work well for my use case and resolved the issue in #53. They also look fine in LabelBuddy.

@adelavega and @jeromedockes is there any additional testing you want to do or are you happy to merge this PR into Main?
