* New last/train module to train alignment parameters.
The last-train command creates a parameter file that
will be used by last/lastal module for sequence alignment.
It takes indexed sequences and query sequences as input
and we use the metadata of both to create an id of the
parameter output file.
Submission of the LAST modules is discussed in more
details in the issue #464. For consistancy, we use LAST
version 1219 for this whole development and will upgrade later.
* Corrected files according to the nf-core v1.14 standards.
* Fixed function.nf file for the last-train module.
* Apply suggestions from code review

* Find index name.
* Correct after the input channels were changed.
* Use double underscore as a name separator.
Single underscores can happen in ids, therefore, we would like to keep two underscores.
* Remove extra spaces.
* Fixed the passing of the "score matrix" line.
* Apply suggestions from code review

* 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
