Add TLS 1.3 early data examples #530
Conversation
Introduces client and server examples that demonstrate the use of TLS 1.3 early data (0-RTT) with session resumption. The client example performs an initial handshake to obtain a session ticket, then reconnects and sends early data. The server example receives early data and sends back a reply.

For null termination

if we receive data here then data is never use, probably it's better to to check and print

This is outdated. Its using wolfSSL_peek now.

did you consider reading 1-RTT data from the server here?

Keeping the example minimal.

but this is very important to showcase minimum latency. Also the server side already writes the 1-rtt data that we never read.
I think adding 1-RTT data from the server completes the example.
