EPG Urls with file attachment not supported

[McChafist]

My IPTV provider provides an EPG URL which has a file attachment.
Unfortunately the DownloadPage function doesn't work for this.

I have had to setup a separate cron job to download the file manually using requests.get in the requests library.
I then point EPG Import to the local file (which is gzipped) and all works well.
Can support for this type of file source be added?
