This PR attempts to minimize guessing of mimetypes, etc. when guesses are compatible.
Essentially, it uses magika and charset_normalizer to guess the StreamInfo. If the guess is compatible with whatever minimal StreamInfo was already provided (no fields contradict), then we combine them and use this as the only guess. If they are not compatible, then we add both -- preferring the information provided by the application/user.
