Expand description

Shared classification for the ff-* crate error types.

Implement severity on each error type; the boolean helpers are derived from it. This lets downstream code branch on recoverability generically:

use ff_format::{FormatError, MediaError, ErrorSeverity};

let err = FormatError::invalid_pixel_format("nope");
assert_eq!(err.severity(), ErrorSeverity::Other);
assert!(!err.is_recoverable());
assert!(!err.is_fatal());
