perf: keep only the image squash when scanning with the squashed scope

Browse Source 
- stereoscope builds a squashed tree for every layer, each a full copy of the one below, so memory
  grows with layers x files. The squashed scope only ever reads the top one.
- new `GetSourceConfig.WithImageSquashOnly(bool)` (and `sourceproviders.Config` field) reads images
  with stereoscope's `image.WithImageSquashOnly`, scoped to that one read
- the CLI turns it on when `--scope squashed` (the default)
- an image source read this way returns an error from `FileResolver` for `all-layers` and
  `deep-squashed` instead of panicking on the missing layer squashes
