POCO C++ Libraries Release 1.13.3 Available

This is another maintenance release, fixing a number of issues.

One important new feature added in this release is support for the vcpkg package manager in the Visual Studio 2019/2022 project files. This should greatly simplify building all of the libraries with external dependencies (OpenSSL, MariaDB client, PostgreSQL client) with Visual Studio.

Please see the CHANGELOG and README.md for more information.
