Axel Meyer 6b2dc22227 Document v0.2.0 API and schema-v2 map format ...

Update README.md to version 0.2.0: add API entries for the 16 new
public functions (encode_gid, decode_gid, upgrade_v1_to_v2,
validate_map_table_v2, atlas_count, atlas_id_at, has_layer, is_indoor,
cell_gid, tile_at_layer, blocks_walk, blocks_sight,
iterate_layers_pre_entities, iterate_layers_post_entities,
draw_map_pre_entities, draw_map_post_entities), add the schema-v2
reference section documenting layer-stack, packed-u32 GID bit layout,
auto-migration, and a v0.2.0 changelog entry.

Fix tile-id OOB validation regression in build_map_v2: after v1->v2
upgrade, packed GIDs were not checked against atlas palette sizes.
Restore the check in build_map_v2 so loading a map with an out-of-range
tile_id still produces a fatal error with the same message pattern.
