Don't require Ktor engine for local image loading

[russellbanks]

I use Kamel to show images that the user selects from their file explorer, but it requires a Ktor engine dependency to do so despite it not needing any HTTP requests for local image loading.

Thank you for this issue. I kept encountering crashes when trying to use kamel. Now I know why

No timeline, but once #51 is implemented this should be resolved

@russellbanks check out implementation("media.kamel:kamel-image-default:1.0.0-beta.1") You can choose pick and choose almost all parts now.... While ktor core is still required, I think it should work without having to add an engine when loading local images
