my_worbook.load() - Consumes a lot of memory #522

Hello,

And it is normal that the "load" function that loads an Excel file, which weighs 12 MB, will take up 1.5 GB of RAM ? 0_0

After 12.8Mb in the end it leads to an error "bad allocation".

There have been some long-standing performance issues with xlnt. I'm going to close all of the old issues in favor of a new umbrella issue https://github.com/tfussell/xlnt/issues/648 where we can discuss options to fix it.
