Description of feature

Description

Add a module for Rasusa, a tool for random downsampling of reads to a target genome coverage or number of bases. This can improve assembly quality or performance.

Goal

• Build an nf-core module that runs rasusa with input FASTQ files
• Support both coverage-based and read-count-based subsampling
• Include test data and documentation
• Provide example use case for ONT and Illumina reads
