Rename RemoveStarSequences to RemoveUnknownSequences
only allow 20 known amino acids
Code improvements

- Use + instead of * in the regex so as to not allow empty strings
- Emmit a warning message if a sequence is being filtered
use one version of bam-rc
use Genome::Info::CodonToAminoAcid to get list of valid amino acids instead of hardcoding them
create regular expression only once
update clinseq blessed.

This build uses bam-readcount0.6 for the clonality step in ClinSeq.
We are transitioning to using just one bam-readcount version inside
ClinSeq and tracking that version in the processing-profile.
