decode_sf

A wrapper function for <code>decode</code> that converts the input polylines,
encoded in the flexible polyline enoding, to simple feature geometries of the sf package.

Binding to the C++ implementation of the flexible polyline
encoding by HERE <https://github.com/heremaps/flexible-polyline>. The
flexible polyline encoding is a lossy compressed representation of a list of
coordinate pairs or coordinate triples. The encoding is achieved by:
(1) Reducing the decimal digits of each value;
(2) encoding only the offset from the previous point;
(3) using variable length for each coordinate delta; and
(4) using 64 URL-safe characters to display the result.
