Description
When we reach the end of the frame we currently return 0, nil (https://github.com/nhooyr/websocket/blob/master/netconn.go#L118). The io.Reader docs discourage this:
Implementations of Read are discouraged from returning a zero byte count with a nil error, except when len(p) == 0.
This seems to have confused other folks as well: #353
My recommendation is we don't return 0, nil and instead block until we get data or a proper error.
