* Update LAST to version 1238.
* Update functions.nf to the latest devel version.
* Update test MD5sums after updating software version.
* Make portable on MacOS
* Allow input alignments to be uncompressed.
While the strategy in this family of modules is to make all inputs and
outputs compressed, this change might be useful to some users.
As of LAST 2138, `last/split` does not allow its input to be compressed.
* Search for .des file, that is guaranteed to be unique.
Some LAST indexes have more than one .bck file and it makes the name
detection crash.
In this commit, I also standardise how the names are detected.
* Use value input channel and optional output channels to handle formats.
As discussed on Slack, it is preferred to use a value input channel
instead of sneaking options through `params.args2` or `params.format`
as we did.
Likewise, optional output channels with clearly labeled format are
preferred to 'catch-all' wildcards.
The `last-postmask` tool distributed with [LAST](https://gitlab.com/mcfrith/last)
filters alignments in a MAF file to remove those with too many masked
(lower-case) positions compared with their score.
As other filter modules like `last/split`, its output file risks to
overwrite its input file as their names are constructed from the sample
ID when multiple filters are chained in the pipeline. I added a check
that gives a clearer error message in this case. Please let me know
what you think about; I can add this test to the existing LAST modules
as well.
This new module is part of the work discribed in Issue #464. During this
development, we fix the version of LAST to 1219 to ensure consistency.
We will upgrade it later.
