SaVi satellite constellation visualizer savi-dev

Adding -all-maps option.

With all-maps, the less useful sinusoidal and cylindrical map projections
are also shown as menu options in the coverage pane.

No-one uses sinusoidal, and cylindrical is far less useful than the
unprojected map added later.

The original map projections in SaVi 1.0 are now deprecated.

Noting current version of Cygwin in use.

Running gcc 7.5 under Ubuntu linux subsystem for Windows.

Making plotStr buffer larger just so gcc 11 stops complaining.

noting testing with gcc 11.2.0, which caused use
of the -fcommon flag in Make to deal with duplicate
header definitions.

This is a kludge; gcc changes suggest headers and includes
need to be reworked.

Increasing buffer size to stop gcc 11 from complaining.

Minor coverage fix to always show 0...n coverage labels when using land/sea mask projection.

Cosmetic change to Telesat script.

Telesat's constellation is now called Lightspeed, so minor tweaks for that.
