Return Int64 from IO#write (Crystal 0.35)

See crystal-lang/crystal#9454

Automatic formatting also did some stuff, I can get rid of that if you don't like it

@jgillich Thanks!

Looks good to me. I'm surprised it actually still compiles on 0.33.0 (that's what CircleCI uses).
Could you update the .circleci/config.yml to 0.35? Then we can merge and release.

[m-o-e]

Not a fan of these blank lines, but if that's what crystal format
wants then, oh well, probably easier to keep them than to argue
with it every time... ;)

@m-o-e Done

@jgillich
Ah! Now there's a warning (see make test output):
Warning: Deprecated OpenSSL::Digest#digest. Use final instead.

Wanna give that a tackle, too? 😬

[jgillich]

Also renamed the method on Checksummer, not sure if that makes sense or not 🤔

[m-o-e]

Yes it does.

Thanks a lot, looks great! 🙇

Will merge, add --error-on-warnings to the test suite
(noticed only now that it's missing) and cut a new release. :)

[jgillich]

Ah, you should also set crystal: ">=0.35.0" in the shard.yml.

[m-o-e]

Yes, I've updated it. Release is out now, please let me know in case you
notice any problems. And thanks again for the help! 👍

[jgillich]

Will do, thanks!
