Zig Taskflow

Attempt at recreating https://github.com/cpp-taskflow/cpp-taskflow in Zig.

Example:

fn func1(x: *const i32) struct { i32 } { return x.* + 1; }
fn func2(x: *const i32) struct { i32 } { return x.* - 2; }
fn func2(x: *const i32) struct { i32 } { return x.* + 3; }

const FlowTask = Task.createTaskType(
    &.{ i32 },
    &.{ i32 },
);
    
var flow = Flow.init(&allocator);
defer flow.free();

var a = try flow.newTask(FlowTask, .{ 1 }, &func1);
var b = try flow.newTask(FlowTask, .{ undefined }, &func2);
var c = try flow.newTask(FlowTask, .{ undefined }, &func3);

try flow.connect(a, 0, b, 0);
try flow.connect(b, 0, c, 0);

try flow.execute();
const result = c.getOutputPtr(0).*;

For a more complete example, see main.zig.
