more description for download files

[Siri101]

As shown in https://github.com/eggnogdb/eggnog_docs/wiki/Description-of-download-files, most download files have corresponding descriptions, but some files like e6.func_profiles.json and e6.seq2ogs.tsv have no descriptions. Looking forward a more detailed descriptions.
