apparently there's no singular sun. there are spot_lights (+light_environment) that function like a sun (directional light).

rtx: work around crash on map load
...
xash tries to render a couple of frames after map has been destroyed and
before the new one was created (R_NewMap called). vk_light expects map
to be there at all times, so it tries to reference things that don't
exist.
boom
here we just check that map exists, and if it doesn't we just skip
referencing lights.
no boom.

we have a limited buffer for string when reading tokens and no way to
specify buffer space. just increase buffer size.
proper fix would be to change ref api to allow passing buffer size as an
argument.
