0.0.8

Different experimental classes have been removed.
If you have used them, they have been moved to the repository: https://github.com/Denisok94/symfony-export

I have removed various classes that I used to automate the export process in one of my projects.
Since I didn't describe their work here, I thought they would be superfluous for others and just take up space.
And I decided that it would be better to put them in a separate repository.
