Avoid integer overflow when summing coefficients #206

Closed 5225225 closed 2 years ago

Fixes https://github.com/image-rs/image/issues/1509

Should this be a checked_add or a wrapping add where we just return something? There looks to be a similar PR https://github.com/image-rs/jpeg-decoder/pull/64/files which did just do a wrapping_add, should this match?
