Feature/gene fusion

[Jorisvansteenbrugge]

This PR adds:

• A new subworkflow to detect gene fusion events by combining two tools (starfusion and arriba) and generating a combined report using fusionreport
  • Including a unit-test
• When a sample is sequenced on multiple lanes, alignment using STAR_ALIGN is now done on fastq files of all lanes together --> This is necessary for starfusion. Previously this was done by mapping lanes individually and then merging the resulting bam files.
  • Including a unit-test
• UMITOOLS dedup workflow is now optional, but enabled by default, to make the pipeline more universally applicable.
• A minimum on the requested run time and memory for SLURM jobs is now included to avoid requesting 1 minute/1mb SLURM jobs that timeout/get killed
