Issue with multiple days for MonthlyDoW

Hi,

First of all, your library is awesome! I do however have issues with multiple days of week in the MontlyDoW schedule.
34 15 * 1,12 2#1,2#L is the cron string I'm using. Parsing fails with:
Days of week: Unexpected character ','.
Now if I leave a single value for days of week such as 34 15 * 1,12 2#1 it works as expected. Is there any way to make it work with multiple values?

Thanks.
Bogdan
