Family Lato not found

[alethere]

Hi there,

Lovely package, it's very nice to have some more aesthetic palettes rather than the dull R ones.
I just wanted to point out that whenever I choose a palette (and thus the image is printed) I get the following warning:

Warning message:
In text.default((n + 1)/2, 1, labels = attr(x, "name"), cex = 1,  :
  font family not found in Windows font database

This is because I don't have "Lato" installed in my computer. Maybe consider using the default font instead to prevent this. Also, currently I can't prevent this warning from popping up if I use the park_palette() function (so I'm using the list directly instead).
