RShiny: Visualize MPAs on the MPA tab

[microlei]

• Load a default MPA country (like Cuba)
• Add tooltip interactivity (to view metadata of each MPA)
• Add filtering capability
• Add selection capability (be able to select multiple MPAs by filtering or clicking/dragging)

Having difficulty rendering some maps. Chile take a really long time and is very sluggish to interact with. USA, Spain and Portugal throw this error:

Error in to_ring.default(x) :
Don't know how to get polygon data from object of class XY,MULTIPOINT,sfg

Other issues with country maps:
Iceland's metadata is pretty sparse, but main issue is there is no name for each region

The javascript rendering engine may not be trying to simplify the polygons. You might try simplifying on the R side before handing the polygons to Shiny/javascript. Perhaps sf::st_simplify() is with a shake. It's hard to know a priori how long simplification will take. So, we might want to precompute and save simplified MPAs and read from those.
