ProxyProtocol usage with TLS

[rmahidhar]

I want to use go-proxyproto with TLS and couldn't find any examples in the repo. Appreciate if you can provide reference code for using go-proxyproto with TLS.

The tests are a good place to look at, eg https://github.com/pires/go-proxyproto/blob/main/protocol_test.go#L954. However, having Go example tests would be a pretty cool addition.
