Error while closing the stream in IPCClient#close

Hello @jagrosh

I'm receiving this error while calling the function `IPCClient#close` which it should close everything safety but it appears an exception that I can't handle it by try and catch because it's in a different thread. So, I hope there's a solution for this error.

```
21:25:26.238 [Thread-11] ERROR com.jagrosh.discordipc.IPCClient - Reading thread encountered an IOException
java.io.IOException: Stream Closed
at java.io.RandomAccessFile.length(Native Method)

```

Start by reading com.jagrosh.discordipc.entities.pipe.WindowsPipe.read at WindowsPipe.java:56 and the reading thread started in IPCClient.java:350. Reproduce closing IPCClient while the reader is active and trace the resulting IOException; done means closing the client no longer produces the reported Stream Closed error.
