Replace cron with cron parser

[Uzlopak]

This is the pendant to agenda/agenda#1150

Switching from ncb000gt/node-cron to harrisiirak/cron-parser for cron-pattern parsing.

Previously month was 0-based (0=January). Going forward standard Unix pattern is used, which is 1-based (1=January).

Please update existing cron-patterns that specify a month (4th position of a pattern). The month is now 1 - 12

1 = January

2 = February

3...

| Example | Execute on 1st of January |
|---------|---------------------------|
| Old     | 0 0 1 **0** *             |
| New     | 0 0 1 **1** *             |
