refactor!: migrate to TypeScript (kelektiv#694)

BREAKING CHANGE: removed `cron.job()` method in favor of `new CronJob(...args)` /
`CronJob.from(argsObject)`
BREAKING CHANGE: removed `cron.time()` method in favor of `new CronTime()`
BREAKING CHANGE: `CronJob`: constructor no longer accepts an object as its first and
only params. Use `CronJob.from(argsObject)` instead.
BREAKING CHANGE: `CronJob`: callbacks are now called in the order they were registered
