inputs/REMIB/Specimen/create.sql: moved filtering out of frameshifted rows to postprocess.sql, where it can happen in an idempotent DELETE. this allows filters to remove additional rows to easily be added on top of the existing filters, without needing to remake Specimen (which takes a long time, because of the many stage I derived columns that get added). the logical inversion inherent in the DELETE condition has been factored through rather than wrapped in NOT (...), because removal of frameshifted rows is more accurately specified as the detection of specific patterns that indicate frameshifting rather than the validation of all fields.
