Does not print pokemon, choice: unown-c

[moiaune]

So I just ran the fortune | pokesay command a few times and then this showed up without any pokemon. Notice the "choice: unown-c".

This was on macOS with version 0.5.3.

Thanks for opening an issue @madsaune! I'll look into this

I've merged a PR that fixes this, thanks for submitting the issue!

When converting the pokesprite pngs -> cowfiles, the img2xterm tool fails to convert some of them and results in empty data. I now skip over these, and I've double-checked that the offenders have been removed
