updated csdp-6.1: Linux and Windows executables are as before, but macOS has
been rebuilt for x86_64 (to accommodate Catalina);
NOTE: current version 6.2.0 caused odd problems with parallel invocations
(e.g. on Ubuntu 18.04);

proper File.platform_path for Windows;

As usual, it has required a bit more tinkering than expected. The Linux and
Windows executables are actually statically linked x86 applications; that
means they might break in a few years. The official 6.2.0 did not really work
