cron_prev function infinite loop on 29 February. Issue occurs in non leap years.

Example infinite loop: Expression: "* * * 29 2 *" Current time: 2021-12-7 12:00:00

Example correct result: Expression: "* * * 29 2 *" Current time: 2020-12-7 12:00:00

@alenloncaric Just tried adding check_next("* * * 29 2 *", "2021-12-07_12:00:00", "2024-02-29_00:00:00"); to the tests and it seems to work as expected (at lease on my toolchain with minor local changes).

Probably it makes sense to check it yourself.

@ghseb He complains about cron_prev and not cron_next.
