Optimize testing process on real-life projects

[Lana243]

Description
We would like to optimize the process of testing on a real-life projects.

Expected behavior
When bug on a real-life project is found it should be easy to reproduce it without a lot of manual work.

Potential solution
The following pipeline should be implemented:

1. Patch the project, modify it to be able to run UTBotCpp GitHub Action on it.
2. Run UTBotCpp GitHub Action on the project.
3. Automatically compare produced csv files with statistics with previous ones.

For this purpose algorithm of automatic comparison of statistic files should be implemented.
