docs: This function acts as a sort key for choosing the highest priority
      effect across multiple genes (so does not assume that effects might
      involve the same start/stop codons).
  
      Returns tuple with the following elements:
          1) Integer priority of the effect type.
          2) Does the associated gene have a "protein_coding" biotype?
              False if no gene is associated with effect.
          3) Does the associated transcript have a "protein_coding" biotype?
              False if no transcript is associated with effect.
          4) Is the associated transcript complete?
              False if no transcript is associated with effect.
          5) CDS length
               This value will be 0 if the effect has no associated transcript
               or if the transcript is noncoding or incomplete
          6) Total length of the transcript
               This value will be 0 intra/intergenic variants effects without
               an associated transcript.
          7) Number of exons
               This value will be 0 intra/intergenic variants effects without
               an associated transcript.
          8) If everything is the same up this point then let's use the very
             sloppy heuristic of preferring transcripts like "TP53-201" over
             "TP53-206", so anything ending with "01" is considered better.
          9) Lastly, if we end up with two transcripts like "TP53-202" and
             "TP53-203", prefer the one with the lowest number in the name.
