- Fix the deploy pipeline

- Update CI files

- `scan_from_url` no longer creates a new directory from the URL. The reason for that is that it makes it harder to predict the directory name and later call `get_file_content`.

- fix `scan_from_url` to work on the cloned repository
- `scan_from_url` now clones to a repository consists of the full URL path

- Refactored the scanning process to utilize multithreading better. This resulted in a big improvement on multi-core systems.
- `scan_from_url` now clones the repository using the `bare` flag to reduce the amount of storage, networking, and CPU needed. This change resulted in a huge performance increase.
- `scan` and `scan_from_url` are now interruptable. That means that it is possible to `crtl+c` for example to stop while in progress.

- introduce a new function `scan_from_url` to support cloning a remote repository and then scan it in a single call.
- put back libgit2 default features to support cloning remote repositories
