Questions about the code

[greggman]

Thanks so much for this library.

I'm hacking some stuff in. I've never used typescript before and I think I might a found a few issues so I thought I'd ask

Also does savedAdlerValue need to be set to undefined here?

png-pong/src/util/arraybuffer-walker.ts

Line 224 in 4d25655

this.adlerStartOffset = undefined;
