Allow filehash 3

[rosiel]

GitHub Issue: #1005

I've tested this and Islandora's code still runs without errors.

The DGI Fixity module still requires 2.x so we're keeping it in here (also makes it compatible with Drupal < 10.2)

What does this Pull Request do?

Allows Filehash 3

What's new?

• Allows Filehash 3
• Does this change add any new dependencies? No
• Does this change require any other modifications to be made to the repository
  (i.e. Regeneration activity, etc.)? no
• Could this change impact execution of existing code? potentially! But my testing showed behaviour stays the same.

How should this be tested?

Put a breakpoint around https://github.com/Islandora/islandora/blob/2.x/islandora.module#L186 and see that you can still access those "fields" on the file entity, and that they return the appropriate checksums.

Also I noted that as before, if you look at the Content > Files list (and edit the view to add Original SHA-1 and SHA-1), any media created by derivatives has a null Original SHA-1.
