Can't download URLs that require special headers, eg. audacity-lame

[laggingreflex]

I get this error when downloading audacity-lame

It seems like it requires some headers to be acquired from their homepage before downloading the installer otherwise it results in a 403. This seems to be specified in it's install file:

chocolateyInstall.ps1

$options =
@{
  Headers = @{
    Accept = 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';
    Referer = 'https://lame.buanzo.org/';
  }
}

When installing directly there's an error at first but it tries again and downloads correctly
