Hi, I'd just like to voice my support for this functionality as another user of `cargo-fuzz`.

I'm often interpreting the input bytes into a some kind of structured input in memory, and when libfuzzer finds an input that triggers a failure in my fuzz target, I'd like to be shown the structured input rather than the byte string that it was interpreted from.

Generally, if one was implementing custom mutations for a structured input, wouldn't one also want to have a custom display for that structured input? They seem to go hand in hand.
