Move uncompressed sequence and metadata files to the data folder

Move uncompressed sequence and metadata files to the `data` folder
instead of the `results` folder. This change aligns with the monkeypox
and zika pipelines, allowing users to safely remove intermediate files
in the 'results' folder while retaining the original input files.
