Release notes

• Breaking change for no_std users: The return type of CryptoProvider::install_default() would change depending on the std crate feature. This was unintended and is corrected in this release. But that does mean this semver-compatible release contains a breaking API change, albeit only for users who omit the std crate feature. Our apologies in advance.
• Performance improvements especially for servers doing a full TLS1.3 handshake, and clients doing a resumed TLS1.2 handshake.
• Improvements to example code: demonstrate usage of TLS1.3 early data (thanks to @tahmid-23) & using clap for CLI.
