Support converting chrono::NativeDate to Dart

[TrackerSB]

Recent updates of the dependency to allo-isolate introduced support chrono::NativeDate in FRB. However, when converting a Rust struct containing a field of type chrono::NativeDate a (working 👍🏻) Dart class which extends from RustOpaque is generated.

Despite the fact that this should be enough to technically utilize the Dart class it would be much nicer if it generated a field of type DateTime instead of depending on RustOpaque. This enables quite more capabilities on the Dart side. In my case especially reflection.

It is still currently worked on trying to keep up with resolving conflicts with origin/master and adapting to CI requirements.
