Pull request opened by <https://github.com/znorgaard|znorgaard>
*Summary*

Adds test data for non-random (fixed) UMI support in nf-core/fastquorum.

*New files*

• *`testdata/fastqs/synthetic-nonrandom-umi/`* — Synthetic paired-end FASTQs (`8M+T 8M+T` read structure) generated from the existing SRR6109255 tiny FASTQs by trimming the original 10bp random UMIs + 1bp spacer, mapping them deterministically to 32 IDT xGen cfDNA fixed UMIs, and introducing 1bp errors in ~10% of UMIs
• *`testdata/umis/idt-xgen-cfdna-umis.txt`* — The 32 IDT xGen cfDNA fixed UMI sequences (8bp each)
• *`testdata/samplesheets/samplesheet.nonrandom.csv`* — Sample sheet where all samples use `umi_file`
• *`testdata/samplesheets/samplesheet.mixed_umis.csv`* — Sample sheet with a mix of fixed UMI (with `umi_file`) and random UMI (without `umi_file`) samples
