optimize calls to number_of_columns() in SheetReader.to_array() #26

Closed ashkulz closed 7 years ago

pyexcel-xlsx uses openpyxl which computes this dynamically, which has a huge performance impact when the number of rows is high.

As discussed in #25, this is targetting the v0.2.x branch.

Looks like the build is broken for another reason, will investigate tomorrow...

Will have look soon. Notice the failure before your pull request.
