[PATCH] [Performance] Share the string table when creating IterableWorksheets
Created originally on Bitbucket by adamlofts
Iterating through sheets in a (large) workbook is very slow in my application. Profiling indicates that 75% of the time is spent inside read_string_table().
Since the string table is built when the workbook is loaded we can simply pass it on to the worksheets.
