Update dependencies to latest versions

[miabbott]

Update all dependencies to latest stable versions:

• github.com/containers/image/v5 (currently v5.4.3 from 2020)
• github.com/klauspost/compress (currently v1.10.4 from 2020)

Run go get -u ./... and go mod tidy.

Note: PR #9 partially addresses this by updating containers/image to v5.29.3. That PR may need rebasing after the Go version update (#22).

Dependencies

• Depends on Update Go version to 1.25+ #22 (Go 1.25+ update)
