More Advanced sync primitives.

Implemented some Go sync primitives.

## Token

provides token implementation.

Only the one thats owns the `Token` can do stuff and then it can handoffs the token to others.

## Batch

provides batch implementation.

It is like `errgroup` and can return all errors results of each task.

## Any

provides partial batch implementation.

You can wait some tasks have finished and returns.

## Stentor

provides pub-sub(observer) pattern.

## Examples

use **syncx** to solve [leetcode concurrency problems](https://leetcode.com/problemset/concurrency/)

- [1115 Print FooBar Alternately](https://leetcode.com/problems/print-foobar-alternately): [solution](https://github.com/smallnest/leetcode/tree/master/1115_print_foobar_alternately)

- [1116 Print Zero Even Odd](https://leetcode.com/problems/print-zero-even-odd): [solution](https://github.com/smallnest/leetcode/tree/master/1116_print_zero_even_odd)

- [1195 Fizz Buzz Multithreaded](https://leetcode.com/problems/fizz-buzz-multithreaded): [solution](https://github.com/smallnest/leetcode/tree/master/1195_fizz_buzz_multithreaded)

## Other advanced sync primitives

- [singleflight](https://github.com/golang/sync/tree/master/singleflight): provides a duplicate function call suppression

- [errgroup](https://github.com/golang/sync/blob/master/errgroup/errgroup.go): provides synchronization, error propagation, and Context cancelation for groups of goroutines working on subtasks of a common task

- [semaphore](https://github.com/golang/sync/tree/master/semaphore): provides a weighted semaphore implementation
