Feature request: Support the “N-th” occurrence of a weekday of the month

[ssd3]

Describe the bug
I need to have the scheduled event for example
At 10 a.m. on the third Monday of every month: 0 10 ? * 2#3

code sample:

startCron("Job 1", {
	what: "Job data 1"
}, "0 10 ? * 2#3", "America/New_York");

Error:
TypeError: CronPattern: configuration entry 5 (2#3) contains illegal characters.

It is possible right now, by setting legacyMode to false and supplying both day of month and weekday, such as * * * 1-7 * SUN for first sunday of month, or 15-21 * SUN for third sunday of month. But I'll keep this as a feature request.

Oh, there is a feature request in discussions already.
