Add support for compressed formats

[panpancho21]

Hi,
please add support for compressed formats, especially LHA, LZX, ZIP.

this feature is planned, just need to understand the best way to do it, since Some plugins have built-in support for Some compressed formats, while personally the best way here would be to handle compressed formats before redirecting the flow to any plugin: a comprehensive lib (eg https://github.com/temisu/ancient ) might be used for this purpose.
