Fix regressions remaining in 3.0.1

[charles-plessy]

Prepare another bugfix release, hopefully the last one for version 3.0

Fixed

• Restore maximum tandem repeat unit length to 400 for genome masking, to prevent running out of memory on centromeric repeats. LASTs default changed to 100 in version 1638, causing a regression in this pipeline's v3.0.0 release (#139)
• Restore missing fasta in the target genome name indexed for CRAM files (#140).
• Avoid collisions by adding .cuts to the name of the file defining the regions of more than 10 Ns in the target genome. (#138).
• Fix blasttab+ export option by correcting Nextflow schema. Thanks, @sapunyangkut (#141).
• Fix blasttab+ format by upgrading LAST to version 1652 (no other changes). For consistency, Samtools and Bcftools were also upgraded (no visible changes expected).
