Belated update this for new API to blast_rbh.py
Update blast_rbh to use BLAST+ 2.2.30

Looks like something has changed in the TBLASTX qcovhsp values?
Update test output using BLAST+ 2.2.30

Note that updating test-data/deltablast_four_human_vs_rhodopsin.xml
will be more complicated...

$ deltablast -query rhodopsin_proteins.fasta -subject four_human_proteins.fasta -evalue 1e-08 -out deltablast_rhodopsin_vs_four_human.tabular -outfmt 6 -rpsdb /data/blastdb/ncbi/cdd/cdd_delta
BLAST engine error: /data/blastdb/ncbi/cdd/cdd_delta contains no frequency ratios needed for composition-based statistics.
Please disable composition-based statistics when searching against /data/blastdb/ncbi/cdd/cdd_delta.
Will bump wrapper versions for BLAST+ 2.2.30
