Adds env_stat/1 which calls mdb_env_info (via lmdb-sys FFI) to return the configured map_size and an approximate used-bytes figure calculated as (last_pgno + 1) * page_size. Callers can compare the two values to detect proximity to the map_size limit before hitting MDB_MAP_FULL. lmdb 0.8 does not wrap mdb_env_info in its safe API, so lmdb-sys is added as an explicit dependency and the call is made through unsafe FFI.
