Thanks a lot, Dustin, both for your work and for your enthustiastic
support. I welcome your contribution.

On the PNG application side, outside of libpng, we have eXIf support
in exiftool (cheers, Phil), and in the proof-of-concept
implementations that some of us here wrote last year while debating
the eXIf spec. But we still have a very long way to go and catch up
with the EXIF support present in other formats, which why I find your
contribution so valuable.

If I'm not mistaken, this is the first Go implementation brought on
png-mng-implement. We are overwhelmingly C-centric. Even mentioning
C++ was a rarity, or Java, an extreme rarity. Bringing a Go
implementation here feels modern and fresh.

If you allow me a bug report:
GOPATH is required, and it shouldn't be. go-exif-knife works fine on
my machine, with the Go development environment set up, but it panics
when I switch that environment off.

Sincerely,
Cosmin
