New Features

• Implements sha224(), sha256(), sha384() and sha512() series of fast, optimised cryptographic hash and HMAC generation functions using the 'Mbed TLS' library.
• ncurl() and stream() gain the argmument 'pem' for optionally specifying a certificate authority certificate chain PEM file for authenticating secure sites.
• ncurl() gains the argument 'request' for specifying response headers to return.
• ncurl() now returns additional $status (response status code) and $headers (response headers) fields.
• messenger() gains the argument 'auth' for authenticating communications based on a pre-shared key.
• random() gains the argument 'n' for generating a vector of random numbers.

Updates

• 'libmbedtls' is now built from source upon install so the package always has TLS support and uses the latest v3.2.1 release. Windows binaries also updated to include TLS support.
• nng_version() now returns the 'Mbed TLS' library version number.
• device() gains a confirmation prompt when running interactively for more safety.
• Fixes issue with ncurl() that caused a 26 cryptography error with certain secure sites using SNI.
