Describe the enhancement you'd like

Some indexers only provide nzbs that are compressed. A major newznab site just changed to nzb.zip and a prominent anime indexer only provides nzb.gz. It would great if there were native support for compressed nzbs for both the incoming file directory for api downloads and when a compressed nzb is uploaded directly to nzbget.

Extra information

I have only seen .zip and .gz nzbs, but please consider adding support for rar, 7z, and the various tar/gz/bz permutations.

There was some discussion here about an extension but the extension does not support all formats and this is suggested core feature functionality

Thank you!
