I have a huge file(>900MB) that I would like to read/process in
chunks.

In clojure, i can grab the first n lines nicely:
(with-open [r (reader "FILE")]  (str-join ", " (take n (line-seq r))))

How can i grab the first n lines starting from an line offset? ex,
grab lines 5 to 10 rather than just the first 5.

I can do this in java using traditional java way by using
LineNumberReader's setLineNumber(int lineNumber)  but i'm not sure how
to interweave this in with clojure's file sequence operations.
