Implement improved meridian distance series from Charles Karney #34

Open busstoptaktik opened 1 year ago

busstoptaktik commented 1 year ago

In PROJ PR 3516, @cffk demonstrated new series expansions for the meridian distance. Rust geodesy currently uses an older implementation by B.R.Bowring. As we have already implemented most of the machinery needed for Karney's work in constants.rs, and in latitudes.rs, we really should implement Karney's work here as well
