* New last/lastdb module to index sequences before alignment.
The `lastdb` command creates a sequence index for the LAST aligner
(https://gitlab.com/mcfrith/last). Input can be in FASTA or FASTQ
format, and compression is handled automagically. DNA or protein
sequences can be indexed.
The sequence index is a collection of files sharing the same basename.
This module sets the basename to the sample identifier (`$meta.id`) and
creates the index in a directory always called `lastdb`. The module's
output channel then conveys a copy of the metadata and the path to the
`lastdb` directory.
Other modules will follow (see Issue #464). The LAST aligner can align
proteins to proteins, DNA to DNA and can translate DNA align to
proteins.
