Description

In some cases, the type of the original isn't clear to the user, especially when it comes to pasting an image.

The type of the original should be indicated.

We should do this by the same mechanism we use to decide which decoder to use (https://github.com/GoogleChromeLabs/squoosh/pull/91#discussion_r201663191).

For formats with broad browser support, I wonder if the mimetype is already populated by sniffing. We should try throwing some extensionless images at the app and see what happens.

Research direction
Examine PR #91 (discussion r201663191) to understand the decoder selection mechanism. Investigate whether the browser's File API provides MIME types for extensionless images by testing with various image files. Then modify the UI to display the original image type using the same logic or by reading the file's MIME type. Focus on files in src/ related to image handling and UI components.
