v0.18.3

Bugfixes! 🐛

1. Return correct sprites
   • Using -n mew no longer returns mewto sprites
   • Using -n natu no longer returns eternatus sprites
   • etc
2. Ensure that duplicate cowfiles are skipped during dockerfile build
   • which created the cows.tar.gz file that is used to build release binaries
   • the binaries now ship with the correct number of sprites
     • 3,547 instead of 5-117

🚀 This (correct once again) reduction in sprites results in a 10% speed uptick on my linux machine, and roughly equivalent speeds on other architectures.
