set timer interval

This section is a work in progress.

Examples:

import {
    Canister,
    Duration,
    ic,
    TimerId,
    Tuple,
    update
} from 'azle/experimental';

export default Canister({
    setTimerIntervals: update(
        [Duration],
        Tuple(TimerId, TimerId),
        (interval) => {
            const functionTimerId = ic.setTimerInterval(interval, callback);

            const capturedValue = '🚩';

            const closureTimerId = ic.setTimerInterval(interval, () => {
                console.log(
                    `closure called and captured value ${capturedValue}`
                );
            });

            return [functionTimerId, closureTimerId];
        }
    )
});

function callback() {
    console.log('callback called');
}
