Stop parsing when cell x has value y

Hi @jacobduijzer, as a first version, something like this #48?
This is lightweight, because it will simply filter out all the data after the first empty row, before starting to parse it.

Hi @josdeweger. Reviewed and approved your solution but it's not the solution I was looking for. With your solution the max number of rows will be read before processing (and potentially stopping when an empty row is seen). I have just created PR #49 which will stop reading the file completely on the first empty row. This shows a serious drop in memory usage when reading the max possible lines from an excel sheet.

Cool stuff, will close this as it is working as expected
