Expose tidy_thumbnail_resize()

[hadley]

• Get active post from rstudioapi
• Resize thumb-sq.jpg to 300x300 (warn if not square)
• Resize thumb-wd.jpg to 200 high and warn if <1000 wide

Hugo also comes with image processing on that end if you would rather: https://gohugo.io/content-management/image-processing/

I did some image resizing on tidymodels.org: https://github.com/tidymodels/tidymodels.org/blob/master/layouts/_default/list.html#L32-L39

The main downside is it creates a new root directory called resources: https://github.com/tidymodels/tidymodels.org/tree/master/resources/_gen/images/books

I think it's slightly better to resize before commit to git (and easy enough to do in R).
