do more data subsets & make vignettes for them

[7yl4r]

• make some maps of ES50 (called es in output df)
  • using global subset
  • using other spatial subsets
  • using full global data
  • using annual (or other datetime) subsets?
  • with different hex sizes
  • using taxa subsets

We want to include interesting (and small) subsets in /data/ and we want to create vignettes showing them off. My notes on creating vignettes

• create new vignettes via usethis::use_vignette("new_vignette_name")
• to pre-build a vignette
  • set chunk's eval is false
  • then put markdown into the vignette to display the output image (or other html)
  • assets go in vignettes or in man/figures [ref)

we may want to divide this issue out into subissues focusing on some of the subset items above.

@sonjagiardina made a really nice vignette on hex resolutions and I am working on one for temporal subsets.
