feat: check if stream matches input format via file signature/structure

[ok-nick]

Adds extra validation before loading the JUMBF to confirm the input format type matches the given stream, otherwise outputting a more specific error.

Some format types such as MP3 and SVG may require a more in-depth structural check.

If we are unsure about mp3 and svg and need more work/verifications, I'd rather we split it out. To avoid taking the risk of breaking (currently working) edge cases.
The corollary is to add good test coverage using real files to raise confidence we covered all cases (is it even possible with mp3?).

[tmathern]

Approving assuming the SVG related question has the same answer as MP3 (please confirm).

I will be changing this PR to perform the support checks as it's being read. This will be much more reliable since we can use our normal parsing methods (like XML for SVG) and it can be done in one pass. We also do this already for some formats, like GIF.
