The report processor doesn't support weekly cumulative frequency and impressions.

[ple13]

Describe the bug
Currently the report processor assumes that the non-total weekly cumulative measurements are the reach measurements. This causes the processor to fail when non-total weekly cumulative measurements do not have reach, or when they have other measurements such as frequency or impressions.

Steps to reproduce
Create a report_summary_v2 where one of the report_summary_set_results does not have reach, the processor crashes.

Component(s) affected
Report Processor

Version
v0.5.29
