Ranked choice votes offer no auditing and can hide write ins

If two voters write in the same candidate, but one mispells it, those votes will not count to the same candidate. There needs to be some mechanism to audit, to make sure a write in isn't being swept under the table because of a situation like this, and there needs to be a way to reconcile and normalise write ins.

issue 中没有指定文件、测试或入口点。首先定位排序选择计票和 write-in 处理，然后确定如何审计选票，以及应如何对拼写错误的 write-in 进行协调。完成的标准是项目拥有一套经过约定的可审计性和规范化机制，并且测试覆盖重复的 write-in 和拼写错误的 write-in。
