Following example code are using Buffer which [has been deprecated since node@6.0.0](https://nodejs.org/dist/latest-v14.x/docs/api/buffer.html#buffer_new_buffer_array) - [./examples/2-datatypes.js](https://github.com/Venemo/node-lmdb/blob/5941c1e553de4ae1d57a67d355b7c2dd87feaea6/examples/2-datatypes.js#L36) - [./examples/4-cursors.js](https://github.com/Venemo/node-lmdb/blob/5941c1e553de4ae1d57a67d355b7c2dd87feaea6/examples/4-cursors.js#L29) - [./examples/8-multiple-cursors-single-transaction.js](https://github.com/Venemo/node-lmdb/blob/5941c1e553de4ae1d57a67d355b7c2dd87feaea6/examples/8-multiple-cursors-single-transaction.js#L29) - and so on. Migrate to the newer [`Buffer.from`](https://nodejs.org/dist/latest-v14.x/docs/api/buffer.html#buffer_static_method_buffer_from_array) API so that these examples can be run on newer versions of node.
