Suncalc usage example

[franpog859]

Hey, @mourner ! I really wanted to thank you for creating this library!

I wanted to show you my little app I created based on your Suncalc. I don't know any better place to share it with you so you can just close this issue immediately, whenever you want 😄

Here is the app itself - https://franpog859.github.io/when-to-shoot/
