Commit Hashes of scraped repos

[ValeKnappich]

@ASvyatkovskiy @micheletufano First of all, thanks for this great resource.

Unfortunately, the dataset does not contain commit hashes of the projects or dates when they were scraped. To calculate the code coverage of generated test cases, you need the whole project. Are the commit hashes saved somewhere and could be made accessible? (or the date of scraping?)
