C# Thrift library forces TLS 1.0, thwarting TLS 1.2 usage

TTLSSocket.cs.setupTLS() uses SslProtocols.Tls, which forces TLS 1.0. I suspect this was originally done to prevent SSLv2 from working against a poorly configured server, but now prevents working against a TLS 1.2 server, thus decreasing security.

Since PCI-DSS requires removing anything less than TLS 1.2 by June, this is a critical issue for those of us working in that environment.

Thanks!
