[Feature request] Handle multiple download sources/mirrors

[o-l-a-v]

Description of the new feature/enhancement

Request

• Ability to add multiple URLs to same installer

Why?

• Speed
  • Example: Foxit CDN is super slow. But they got two CDNs. Forces combined, 2x super slow = slow.
• Reliability, redundance.

Example

• https://cdn01.foxitsoftware.com/product/reader/desktop/win/11.0.1/FoxitPDFReader1101_L10N_Setup_Prom.exe
• https://cdn02.foxitsoftware.com/product/reader/desktop/win/11.0.1/FoxitPDFReader1101_L10N_Setup_Prom.exe

Potential blocker

• Requires complex download logic that might not be in place already?
  • Free Download Manager manages it for instance
    

Proposed technical implementation details (optional)

• Update cli to handle the download logic, if not already implemented.
• Update manifest scheme to accept one or multiple URLs to the same file.

The problem with this is it complicates verifying the download and any retry logic

Maybe one could use a open source downloader like aria2?

• https://github.com/aria2/aria2

And use exit code + checksum to verify success.

• Support downloading packages in parallel, with multiple connections per package (similar to apt-fast) #225
• Add a check for packages distributed via sourceforge to check if a mirror link is used in yaml file #673

Similor issue with KiCad, Different mirrors has different bandwidth available depending on the location you are downloading from. Default github source is very very slow.
