Example for Deserializer uses `bytes_read` method which doesn't exist

[joshtriplett]

The sample code for bincode::Deserializer uses a bytes_read, which doesn't exist and appears to have been removed years ago.

The Deserializer documentation is still wrong as of current master.

The bytes_read reference was removed in b9e3a8001ca1c7b01a39a906d8ce566c035b5be6. I think this can be closed.

I'm okay with waiting on keeping this issue open until bincode 2 has been properly released. Currently we're still in 2.0-alpha and could possibly do 1.x releases
