Some stations cause Unicode errors when parsing headers

[AzureKitsune]

A station named Conect Rádio 64k AAC
(http://142.4.222.227:9890/) is causing an exception when connecting due to a Unicode issue.

Exception:
Message: No mapping for the Unicode character exists in the target multi-byte code page.
Stack Trace: None but it comes from this line in ShoutcastMediaSourceManager

while (!response.EndsWith(Environment.NewLine + Environment.NewLine))
{
    await socketReader.LoadAsync(1);
    response += socketReader.ReadString(1);
}

Its possible that #5 will fix this.
