biocodeutils.py add error output mRNA ID

[ktretina]

When the biocodeutils function called "translate" finds an unknown codon, it currently will deal with it like this:

print("WARN: Encountered unknown codon during translation: {0}".format(seq[x:x+3]))

Could you please add the mRNA ID to this output? I think you'll have to add that to the function input. This will help when trying to track down the sequences with this issue.

Thanks!
