Addition of filetypes for static downloads

This is similar to :

I’d like .whl and .asc to be added to the list of static downloads. Can they be added to the list? For context if necessary, I’m tracking downloads from a private PyPi server.

Additionally, is there an accepted way to add extensions at a per-instance level? I’m fine with changing the list in, but I’m not sure if there is anything else in the code base which needs to be tweaked.

As an example, GoAccess allows specifying static file extensions with

     Add static file extension. e.g.: .mp3 . 
     Extensions are case sensitive.
