new marine style verstaerker-oseam

Hi,

please find a new marine style and a gmapsupp.img image (Northern Germany and Denmark) for testing at:

https://github.com/verstaerker-583/verstaerker-oseam
https://github.com/verstaerker-583/verstaerker-oseam/blob/master/gmapsupp.img.xz

This is the area covered by the test image:

https://extract.bbbike.org/?sw_lng=05.8663153&sw_lat=53.0110367&ne_lng=15.0419319&ne_lat=57.9524297

Almost all extended marine types assigned to osm tags:

  • obstacles (obstacles, rocks, wrecks) with depth, depth flag (!!!)
  • height for landmarks, bridges and overhead cables
  • spot depths with correct values
  • (river/ canal) distance marks, which are searchable as „mile markers“ on marine devices
  • navigation lines
  • lights with leading angles, and some hacks for lights with missing colour, rangle or sector information
  • most landmark categories
  • detailed (restricted) area support
  • shoreline constructions (piers, docks, …) with filled areas
  • decent traffic separation schemes - unfortunately still no arrows
  • basic small_craft_facility to gamin facility type implementation

Feedback and suggestions will be highly welcomed.

Olaf
