In dankelley/oce: Analysis of Oceanographic Data

Two things are being done in this directory (see https://github.com/dankelley/oce/discussions/1756 for discussion).

1. Create a high-resolution dataset for the Nova Scotia region.
2. Solve a problem with plotting topo with GEBCO colours. Originally, before 2020-12-14, shallow waters were being plotted with a reddish (land-like) hue. This was basically because the palette is constructed by blending colours, and the water colours are bluish, while the land ones are reddish, but mixing blue and red does not yield white. I solved this by adding a white band, although I found that band to be too wide in tests, so I first expanded the 9-element water and land bands to be longer. See the above-named website for details.

NOTE: the new datafile, called topoNS.rda for now, is 87K (was 163K before compression).
