• Support PHP 8.5

• Fix a bug that could prevent objects/arrays with reference cycles from being properly garbage collected.
• Fix bugs in unserializing PHP references to values found in php 7.4 typed properties (#363)

NOTE: The PHP for Windows team is working on getting dlls built again for pecl extensions. Those should be used instead on Windows once they are available. See https://windows.php.net/

DLLs for Windows can temporarily be found at https://github.com/igbinary/igbinary/actions/workflows/build_dlls.yml (under "Assets")

• Add a macro that callers can use to check if igbinary will accept the header for data being unserialized.
• Fix bug preventing the unserialization of data containing representations of strings larger than 4GB.

• Reduce excessive inlining to reduce shared library size.
• Miscellaneous optimizations.
• Update test expectations to handle changes to var_export output (fully qualified class names) in PHP 8.2.
• Throw an Error when igbinary_unserialize would add dynamic properties to class definitions that forbid them in PHP 8.0+
  (especially PHP 8.2 readonly classes)
• Emit a deprecation notice when igbinary_unserialize() adds dynamic properties to a class without #[AllowDynamicProperties] in PHP 8.2.
  Doing that would become an Error in PHP 9.0.
• Set up CI job to build dlls on https://github.com/igbinary/igbinary - at the moment, the infrastructure used by the Windows for php team has been broken for months.
