C2PA Content Credentials Extension

Content Credentials add machine-readable and verifiable manifests to online assets to track the origin and history of online assets using the C2PA standard.
When right-clicking on an image (jpg), video (mpeg) or audio file (wav or mp3) and selecting the `Verify Content Credentials` menu, this extension checks for manifests attached to the assets. If an asset has a manifest, the extension will validate it and make the results available via a click on the Content Credentials “CR” pin icon.

Features:
- Right click on an image, video or audio clip and select `Verify Content Credentials` to trigger the verification.
- Or toggle on or off the automatic detection of assets with manifests.
- Validates manifest when present and adds a \"CR\" pin to the assets.
- Hovering the \"CR\" pin displays a summary of the manifest in a pop up
