CDS and mRNA seq extraction doesn't respect codon_start

[hyphaltip]

This line retrieves / respects the codon_start when generating the protein translation. however the lines which establish the coding seq in first place don't - so we should probably move this upstream in some way to slice off codon_start nucleotides from the coding sequence so it can be translateable.
