Package mapsoft2: Information

- switch to new libproj API;
- ms2conv: modify --join option
- ms2geofig: add srtm data, add raster maps
- ms2view: a few fixes of panoramic veiw

- Drawing tracks: --trk_draw_width option
- Downloading tiled maps: --insecure, --user_agent, --http_ref options
- Making map reference: --coords_nom, --coords_file options
- TIFF: --tiff_compression option -- support many compression types
- better support for ALOS DEM files
- FIG/GeoFIG support
- fix build with gcc12.1.1

- Drawing maps, tracks, waypoints, srtm-data:
    Fix projection setting if map boundaries can not be converted.
    Fix adjusting waypolit lable positions, avoid infinite loops.
    Fix multi-thread locking in waypoint rendering.
    Fix default track color (blue).
    Fix drawing summit labels on tiles (srtm layer).
    Use srtm_bgcolor if picture is out-of-scale
    When drawing tiled maps do not fail at empty images, return color 0
- Geodata, geo-conversions:
  - Read-only support for Polygon/MultiPolygon features in GeoJSON.
  - New alias: SU<n>N for soviet grid without zone prefix.
- Creating map references (mkref):
  - Allow floating-point arguments in --mag and --dpi options when creating a map.
  - Add --north option for --mkref=nom.
  - Set default border in "tiles" and "proj" modes.
- Vector maps:
  - Add `clip` drawing feature: set clipping for all following steps
  - Value of --clip-border setting is not changing then configuring `brd`
    step, it also affects out-of-scale filling.
  - Add `fit_patt_size` drawing option.
  - Always load patterns at original size.
  - Fix a few problems with pattern rendering.
  - Support lable scaling (import/export/rendering).
- Rendering tiles:
  - Always crop tile range to [0,0,2^z,2^z]
  - Create sub-directories when creating tiles, allow tile templates with subdirs
    (thanks to @ioctl).
  - A few optimizations for creating tile maps (thanks to @ioctl):
    do not create empty tiles, do not re-assemble old tiles in --tmap_scale mode,
    a bit faster color quantization.
- geo_nom, geo_tiles:
  - ms2nom: -W option: use WGS coordinates in calculations.
  - Fix problems with crossing lon=+180/-180 
  - Add --cover option with figure or geo-file argument (thanks to @ioctl).
