What addr to use for reflector wallet.Connect

Nobody has claimed this yet.

Hi, I wanted to use LBRY through golang, but the lack of good documentation makes it really hard for me.

What address should I use to connect with wallet serwer? I tried using these urls:
https://github.com/lbryio/lbry-sdk/blob/7a8d5da0e8df0244bafbfd03acd4403557608dcb/lbry/conf.py#L689
but I get panic `dial tcp 147.135.1.20:50001: i/o timeout`

My code:
```go
var r *pb.Output
var err error

addr := []string{
"spv11.lbry.com:50001",
"spv12.lbry.com:50001",
"spv13.lbry.com:50001",
"spv14.lbry.com:50001",
"spv15.lbry.com:50001",
"spv16.lbry.com:50001",
"spv17.lbry.com:50001",
"spv18.lbry.com:50001",
"spv19.lbry.com:50001",
}
w := wallet.NewNode()
defer w.Shutdown()

if err = w.Connect(addr, nil); err != nil {
panic(err)
}

```

Start with the wallet.NewNode and wallet.Connect entry points shown in the Go example, and compare their expected server address format with the referenced lbry/conf.py configuration. Confirm which endpoint information is current, then document the supported address and connection guidance for Go users.
