+Create `formatPlatform` and `formatAllPlatforms` methods.
+This will return the outputs and destinations from the format hook for your dictionary, without building these outputs and persisting them to the filesystem.
+Additionally, formats can now return any data type instead of requiring it to be a `string` and `destination` property in `files` is now optional.
+This allows users to create formats intended for only formatting tokens and letting users do stuff with it during runtime rather than writing to files.
