* 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. * Remove trailing whitespace. * Apply suggestions from code review Co-authored-by: Harshil Patel <drpatelh@users.noreply.github.com> * Update as suggested in PR. * Attempt to pass linting.
