fix constellation compilation error

[PLAZMAMA]

Currently I have a bug when I try to compile constellation on clang v14.0.6.

The following is the error I get

(.venv) ⎇ improve_boids_4.0* ~/src/PufferLib=> ./build.sh constellation --local
Compiling constellation...
warning: unknown warning option '-Werror=array-parameter'; did you mean '-Werror=unused-parameter'? [-Wunknown-warning-option]
constellation/constellation.c:185:19: error: initializer element is not a compile-time constant
    .font_color = PUFF_WHITE,
                  ^~~~~~~~~~
1 warning and 1 error generated.
warning: unknown warning option '-Werror=array-parameter'; did you mean '-Werror=unused-parameter'? [-Wunknown-warning-option]
1 warning generated.

I fixed it by just "# defining" the colors

Sorry for the redundant white space deletions... My editor did that.
