STTP C++ API v1.0.20

See build steps to create a platform specific library.

Updates:

• Updated all string to numeric, boolean, Guid and timestamp conversions to use TryParse style operations -- prevents possible exceptions with malformed metadata

• Fixed exception in data publisher when no filterExpression is provided in connection string from a subscriber
• Fixed conversion to boolean targets in filter expressions
• Fixed reverse filter expression function to operate properly
• Updated filter expression functions that return null for null primary input to handle null return before any non-null validation of remaining parameters
• Updated data publisher to be restartable after a call to stop
• Updated data publisher to handle calls to Stop a separate shutdown thread to prevent issues where user may call stop method from a dispatched event thread
• Improved data publisher shutdown operations

• Added TryParseUInt32 to convert functions
• Updated socket related asio delegates to use templated lambdas
• Updated fractional second operations to use integer division
• Updated ANTLR CPP runtime to version 4.9
• Updated pugixml version to 1.11
• Updated code to support boost v1.75 -- this required custom include file to fix duplicate symbol errors during link
• Switched unicode conversions to nemtrif UTF8 library as wstring_convert is deprecated in C++17
• Migrated headers to use "#pragma once" instead of old-style include guards
• Updated code to support C++20
• Updated code per clang suggestions
• Added additional comments to TSSC algorithm for inclusion in IEEE 2664 standard
