Implement wink2 inverse by generic inversion of forward method

2020-05-28T11:51:28+00:00

- Move the generic method initiated from adams_ws2 to a
  pj_generic_inverse_2d() method
- Use it in adams_ws2
- Use it in wink2

Zone Definition Fixes for igh_o projection (#2233)

2020-05-19T15:22:04+00:00

Implemented IGH Oceanic View (#2226)

2020-05-19T00:04:04+00:00

- The current implementation of the Interrupted Goode Homolosine
  projection emphasizes land area. This is a compliment projection
  that emphasizes ocean area.
- A value of lon0=-160 produces a reasonable real-world map.
