allow non-queryset iterators in excel/csv writers

[AlexCLeduc]

• added new writer classes so you can work with non-queryset based iterators (in practice this will probably still be models, but sometimes you want to evaluate it to a list so you can perform aggregate python logic)
• Added and modified tests around the excel/csv utils to maximize coverage
• bumped major version because of breaking change in excel utility
