alro65 750d4ecbd2 Rediseñar símbolos BCNLAT y LIGHTS + land Barranquilla 
BCNLAT (_encBeaconCanvas): rectángulo delgado y alto en color IALA.
  Babor  (puerto, verde IALA-B): tope plano = rectángulo puro.
  Estribor (estribor, rojo IALA-B): tope triangular apuntando arriba +
  cuerpo rectangular debajo. Gradiente lateral 3-D. Aplica igual a
  daymarks del ICW Miami y balizas de orilla Colombia.

LIGHTS blanco (_ialaLight): rectángulo cuerpo blanco borde negro,
  estrella de 5 puntas centrada, lagrima estirada purpura a ~20° de
  la vertical saliendo del costado superior del rectángulo (S-52 style).

land.geojson BARRANQUILLA: polígono único trazando la costa desde
  Galerazamba (O) hasta la boca del canal Bocas de Ceniza (E),
  incluyendo ambas riberas del canal y la costa sur hasta el límite
  de la carta. Corrige tierra en 0 features.
