After inserting an entry with `key = [0x0?, 0x??, 0x??, 0x??]`, the entry does not get returned by `getRange` and similar functions. ```ts import lmdb from "lmdb"; const rootDb = lmdb.open({ path: './lmdbtest1', encoding: 'binary', keyEncoding: 'binary', }); const subDb = rootDb.openDB({ name: 'sub1' , encoding: 'binary', keyEncoding: 'binary'}); const buffer = Buffer.allocUnsafe(4); buffer.writeUInt32BE(1, 0); subDb.put(buffer, buffer); console.log(Array.from(subDb.getRange())); // Empty. console.log(subDb.get(buffer)); // Not empty. ```
