feat: allow zipped input files

[ninsch3000]

currently the workflow only works for unzipped fasta files as input, as the used bedtools container in the process sequence_extractor cannot handle gzipped files. For storage space reasons it would be beneficial to use zipped files though
Either introduce a process/command within a process to unzip input files and zip output files later, or find a bedtools container that works with zipped fasta files.
