✨ Understand `image:tag` syntax

[shnizzedy]

Related problem

cpac only takes --image and --tag separately

Proposed feature

If image:tag syntax is provided to either, cpac could parse it out. If it gets multiple definitions (e.g., --image image:tag --tag tag, it can continue if there's no conflict or crash out if the tags don't match.

Acceptance criteria

• --image image works
• --tag tag works
• --image image --tag tag works
• --image image:tag works
• --image image:tag --tag tag works
• --image image --tag image:tag works
• --image image:tag --tag image:tag works
• --tag image:tag works
