v4.0.3

Improvements

• Support for nullable value types in #1460
  • This adds support for optional like types that cannot provide an operator bool() because that operator is reserved for some other action. This adds a nullable_value_t concept that only checks for value() and has_value().
• Adding glz::convert_struct for reflection conversion in #1472
• Faster glz::validate_json in #1478
• Use constructible_from rather than convertible to string_view in #1486
• Cleanup and minor optimizations by @stephenberry in #1461, #1462, #1464, #1475, #1479

Fixes

• Fix issue with variants of 1 type and tags in #1485
• validate_skipped for glz::validate_jsonc in #1476

In Development

• Improvements to glz::async_map in #1465
• async_map -> shared_async_map in #1469
