(Feature Request) Unreal: Listing or iterating through all fields In a UObject

[PARTYMANX]

While working on the THPS 1+2/3+4 autosplitter, when starting to adopt UObject field names to find offsets (and more directly, #112), but found it difficult to actually figure out what I was looking for. It was useful to modify the asr crate to list all fields in a given UObject for me.

For example, to UObject, I added the following:

pub fn list_fields(&self, process: &Process, module: &Module) {
    let name = self.get_fname::<CSTR>(process, module).unwrap().validate_utf8().unwrap().to_string();
    crate::print_message(&format!("Fields for UObject {}:", name));

    self.get_uclass(process, module)
        .unwrap()
        .list_fields(process, module);

    crate::print_message(&format!(""));
}

and to UClass,

fn list_fields(
    &self,
    process: &Process,
    module: &Module,
) {
    for field in self.properties(process, module) {
        let name = field.get_fname::<CSTR>(process, module).unwrap().validate_utf8().unwrap().to_string();
        let offset = field.get_offset(process, module).unwrap();

        crate::print_message(&format!("{}: offset {:#018x}", name, offset));
    }
}

Obviously this solution isn't great as it relies upon alloc. I think the ideal solution is to expose the iterator and allow the user to do anything for each entry. I don't really have the time to iterate upon it right now to make a proper pull request so I'm making this issue to present the idea.
