terrainr 0.7.2

• New features:
  • Two new endpoints are available: HRO, which provides orthoimagery for
    non-CONUS US domains, and USGSNAIPImagery, which only returns NAIP
    (whereas USGSNAIPPlus, the default for ortho, will use HRO where
    appropriate).
• Improvements and bug fixes:
  • Updated NAIP URL to its new home, which should reenable NAIP downloads.
  • Fixed warning in geom_spatial_rgb() about "dropped aesthetics".
  • Fixed govunits test.
• Dependency changes:
  • ggplot2 now requires a minimum of 3.4.0
