Fedivuln

- The client [PyVulnerabilityLookup](https://github.com/cve-search/PyVulnerabilityLookup) is now used in order to communicate with
the API of the Vulnerability-Lookup instance.
- When a duplicate sighting is detected a message is printed.
- Improved management of UTC aware Datetime objects.

The new command FediVuln-Search enables searching for users, tags, and—when supported by the Mastodon instance—full text. By default, searches are limited to your own posts and those you've interacted with.

The FediVuln-Stream command now includes a --push-sighting parameter, allowing filtered sightings to be sent directly to a Vulnerability Lookup instance. Additionally, FediVuln-Stream can retrieve streams from a specific user or the public feed associated with the instance or connected user.

This release introduces detection of vulnerability IDs from the Global Security Database (GSD), CSAF Red Hat, CSAF Cisco, and CSAF CERT-Bund.
