Merge pull request #5596 from stulle123/update-file-size

Increase the max file size of parsed *.txt files to 500 kilobytes. 
The limit exists to prevent ingesting documentation files etc that are massive.

However, the previous limit of 200 KB was too small... Especially in large projects,
pip-tools-compiled requirement.txt files can get pretty big.
