External Download Manager for Archiver

[anyabot]

功能描述 / Feature description

Thanks for fixing Archive Download. It works most of the times, but there are still some problems I found.

• Sometimes the download just doesn't start (It fails immediately, and restarting doesn't work).
• Sometimes after finishing the download, the app can't open it (it shows the "request access to location" a few times, then load the reader but everything is blank, the file is downloaded successfully and can be opened normally with other apps).

I also want to enable to useage of External Download Manager (ADM, 1DM+) for Archiver Download. It would be easier to download large files and able to resume download later without having to keep FEH running in the background.
