• adds support for zig-0.15

This is now valid:

const Simple {
    name: []const u8,
};

var arena = std.heap.ArenaAllocator.init(gpa);
defer arena.deinit();

var parsed: Simple = blk: {
    const source = try gpa.alloc(u8, file_size);
    defer gpa.free(source);

    _ = try file.preadAll(source, 0);

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

    try yaml.load(gpa);...

• adds support for zig-0.14.0
• makes the parser faster and more cache friendly by embracing data-oriented design (https://github.com/kubkon/zig-yaml/pull/59)
• ⚠️ breaking ⚠️ reorganises the public API (https://github.com/kubkon/zig-yaml/pull/64)
• provides semantically meaningful parsing errors accessible out-of-band (https://github.com/kubkon/zig-yaml/pull/68)

Support Zig 0.13.0 release.
