send() succeeds silently when underlying websocket is not initialized yet

https://github.com/pladaria/reconnecting-websocket/blob/9b3eaee429253eb92d0f7e6aec38ac953ef681a3/reconnecting-websocket.ts#L220

    /**
     * Enqueues the specified data to be transmitted to the server over the WebSocket connection
     */
    public send(data: string | ArrayBuffer | Blob | ArrayBufferView) {
        if (this._ws) {
            this._ws.send(data);
        }
    }

Result: message is lost, but application code thinks everything is OK.

Real-life example of such occurrence:

const socket = new ReconnectingWebSocket(url);
// The main thread continues execution before ReconnectingWebSocket._ws is initialized.
// Maybe because of setTimeout() and Promises in ReconnectingWebSocket._connect logic?
socket.send("MSG");
// No exceptions, all send() calls are lost before _ws is initialized

I'm sorry, but because of this and #60 there is no way this supposedly very useful library is suited for any dependable production usage.

Hi, sorry for the inconveniences. This and the other issue should be fixed in next release.

Thanks for reporting!
