rename 'rfi_percentage' to 'rfi_percent' for imaging compression pipeline

In the new imaging compression pipeline runs this value will be called 'rfi_percent'.

This means that the old runs will no longer show a 'calculated quality' in the summary now, but that doesn't crash anything. Stakeholders were okay that this is not backward compatible, because so far only test runs have been done.
