Blast format help message is outdated

https://github.com/biocore/sortmerna/blob/4405830700ca14485aa2d4081d69cac87c429dbd/include/options.hpp#L147

In sortmerna help message, blast output is indicated as (Blast - m 8 format). This corresponds to an outdated version of Blast, not in use anymore for more than 10 years.
The current version of BLAST is Blast+ NCBI. In this version, the tabular format corresponds to -outfmt 6.

Therefore, I suggest the help message be modified to
'1' - tabular(Blast+ -outfmt 6 format)

Hi,

It would be nice to add header in the blast output files. I could not find to what correspond each column.

Best regards
