Reading CSV: Add feature to skip N rows at the top of the file #337

I'm working some pricing files from Carnival Cruise and they all have some dumb extra sort of "comment" line at the top of every CSV file that simply needs skipped. The NEXT line are the headers.

Ex: 

Date:  10302023  Time: 02:01 EST VERSION
Category,Meta,Category description,
FA,INTERIOR,FAMILY INTERIOR,
HA,INTERIOR,HAVANA INTERIOR,
TA,INTERIOR,HAVANA INTERIOR,
4S,INTERIOR,SPA INTERIOR,
4T,INTERIOR,SPA INTERIOR,
4A,INTERIOR,STANDARD INTERIOR,
4B,INTERIOR,STANDARD INTERIOR,
4C,INTERIOR,STANDARD INTERIOR,
4D,INTERIOR,STANDARD INTERIOR,
4E,INTERIOR,STANDARD INTERIOR,

I would suggest some feature to skip an arbitrary number of lines at the start of the file which would boil down to just calling iterator.next() that many times to skip.
