Report generation performance improvements

[andrcuns]

⚠️ Breaking change ⚠️

• Removes filesystem copy operation which in case of large reports can significantly slow down report generation.

This changes --results-glob behaviour. It now must return a list of folders containing allure results instead of returning list of files.

Closes: #355
