#145 Follow Up: Update the `ImageRegistry` source's `Unpack()` method asynchronous

[everettraven]

Following operator-framework/catalogd#145, we should update the Unpack() method of ImageRegistry source to be asynchronous. This will ensure we don't create a reconciliation loop block on the actual pulling and layer unpacking of the catalog image.

Acceptance Criteria:

• The Unpack() method of the ImageRegistry source is asynchronous
