New last/split module to find split alignments. (#511)
* New last/split module to find split alignments.

The `last-split` tool distributed with [LAST](https://gitlab.com/mcfrith/last)
finds split or spliced alignments in a MAF file that is produced with, for
example, LAST `lastal` command.

This new module is part of the work discribed in Issue #464. During this
development, we fix the versiob of LAST to 1219 to ensure consistency. We will
upgrade it later.

* Update software/last/split/main.nf

* Apply suggestions from code review
