Working skeleton of the tab separated turnout reports

[JohnMwashuma]

Context

---

This is a working skeleton of the turnout report described in these docs. https://docs.google.com/spreadsheets/d/1YnykTc6-MYjokM15VRmZcSWnBS-JESA1eTEhDEivVu8/edit#gid=1805275455 https://docs.google.com/document/d/151tS0rlJpywFSrLDmr-Gtmz6PSNApv_Vbz67IsWbdX8/edit

This work was to test if it's possible to have the reports in one page and tab separated, which we've managed to do. Also due to the complexity of the report queries, specifically finding voters voted in the counted stations we had to use plain functional views so that we can return a list of dictionary objects. This means we do not have the inbuilt functions provided by django datatables lib e.g. page size changes, page changes e.t.c. However these shouldn't be hard to build.

That said, I think we can build on top of this work and finish the pending items.
