Fixed 'Invalid non-string/buffer chunk' error when using Uint8Array

[e-avidan]

Using 'new Buffer' on a Uint8Array does not create a Buffer object, but adding a Uint8Array chunk is supported by the library, so I added a check to the validation to allow this

They try to achieve the same thing (I think), but this approach would just let Uint8Arrays pass through to the _read() method instead of adjusting its prototype. I don’t think that’s a good idea.
