Update: AnalyticsUploader - refactor how we accumulate data - AnalyticsTable no longer serializes EventRecords, that's moved to IAccumulators - Implement serializers on top of IAccumulators (Csv, Json, CompressedCsv, CompressedJson) - Uploaders automatically create IAccumulators per AnalyticsTable Still missing an accumulator that would replicate how client analytics are serialized, but now it should be easy to do. Unit tests got simplified, need to expand coverage Tests: ran unit tests
