This change more or less completely changes how `ko://` is handled internally to `ko`, but the user-facing changes should only be net-positive. `ko://` was previously stripped at the highest level, and the build logic was unaware, which had some undesirable diagnostic/functional implications that are collectively addressed in this change. With this change, the `ko://` prefix is preserved and passed to the build logic, which internally parses a new `reference` type (this was useful to have Go's type checker find all of the places that needed fixing). The main functional differences are: 1. If a reference is prefixed with `ko://` we will now fail fast in `IsSupportedReference` regardless of whether `--strict` is passed. 2. If a reference is prefixed with `ko://` it will bypass the prefix check, which allows the use of `ko://github.com/another/repo` that references a vendored binary package. For `2.` the absence of the module prefix causes the filtering logic Jon introduced to avoid the reference. This was critical for efficiency when `ko://` isn't around because we feed every string in the yaml through it, but when the user has explicitly decorated things it's the perfect thing to be sensitive to.
