Finish cable analysis for country

[bbest]

Mostly there with commit https://github.com/ecoquants/nrel-cables/commit/ccc6b83129b48ca4ce056dd1dde1771cdfe1aea9 containing docs/create_cable-buffer.R, but need to fix issues:

• [x] Spurious lines span dateline:

  • FIX: reduce extent so doesn’t overlap dateline
  • LK: tiling over Pacific overkill since looking at most 200nm offshore, ie MarineRegions.org US EEZ -- probably w/ inland buffer so not removing coastal mismatched slivers

• [x] *Missing tiles for buffer 3depth**

  • Identify which index are missing tiles (n=32), so make a little map of tiles to show how Albers projection used to reduce distortion
  • FIX: try clgeo_Clean(strategy = "POLYGONATION") Intersection at tiles

• [ ] Intersection at tiles, eg buf_2xdepth-incr100m.geojson

Looking pretty good with Google Earth sanity check:
