Struct's default value not being used

[drone-ah]

Hi,

I'm considering using zig-yaml for a little side project I'm working on. One of the features I would like is the initialisation of the struct with its default values if it is missing from the yaml file.

I've made a variation of the sample from the README.md

test "yaml" {
    const Yaml = @import("yaml").Yaml;
    const source =
        \\names: [ John Doe, MacIntosh, Jane Austin ]
        \\numbers:
        \\  - 10
        \\  - -8
        \\  - 6
        \\nested:
        \\  wick: john doe
        \\finally: [ 8.17,
        \\           19.78      , 17 ,
        \\           21 ]
    ;
    const allocator = std.testing.allocator;
    var arena = std.heap.ArenaAllocator.init(allocator);
    defer arena.deinit();

    var yaml: Yaml = .{ .source = source };
    defer yaml.deinit(allocator);

    try yaml.load(allocator);
    const Simple = struct {
        names: []const []const u8,
        numbers: []const i16,
        nested: struct {
            some: []const u8 = "some",
            wick: []const u8,
        },
        finally: [4]f16,
    };

    const simple = try yaml.parse(arena.allocator(), Simple);
    try std.testing.expectEqual(simple.names.len, 3);
    std.debug.print("### {} \n {s}\n", .{ simple, simple.nested.some });
}

This test currently fails for me:)

I see that https://github.com/kubkon/zig-yaml/issues/85 was closed with https://github.com/kubkon/zig-yaml/pull/86 getting merged in. I thought this was bringing in precisely this feature.

I am (as far as I know), using the latest commit:

zig fetch --save=yaml https://github.com/kubkon/zig-yaml/archive/47aed6a945d1eaeb47d63b7f10b8f68ad6e37820.tar.gz

I am pretty new to zig, so it's entirely likely that I'm doing something wrong - and I'd appreciate some assistance in resolving this.

Thanks & Best Wishes

Should be fixed by #97
