Danila Poyarkov 53b98d76c4 Add MLT (MapLibre Tile) output format ...

Integrate the C++ MLT encoder from maplibre-tile-spec as a submodule.
Tiles are encoded by converting the existing mvt_tile to
mlt::Encoder::Layer and calling the encoder library directly.

New CLI flags:
  --output-format=mlt     Encode tiles as MLT instead of MVT
  --pretessellate         Pre-triangulate polygons (MLT only)
  --no-mlt-feature-sort   Disable within-tile Hilbert sorting (MLT only)

MLT tiles use .mlt extension in directory output and format=mlt in
mbtiles metadata. Compression and all existing flags work unchanged.
