Multiple favicon input sources

[quittle]

Is your feature request related to a problem? Please describe.
For a project, I have a busy logo at a high resolution but it looks terrible as a favicon. I have a stripped-down version that's a lot simpler and looks good when rendered at 16x16. Because this plugin generates icons at various sizes, it would be great if I could provide multiple source images and have the plugin choose the most appropriate image given the size.

Describe the solution you'd like
Provide an Array<string> or { int: string } with the different icon sizes so the plugin chooses the smallest image >= a targetted image size for each output.

Describe alternatives you've considered

• Manually generating all the files
• Give up - Only generating small icons with the simplified icon
• Give up - Using a large version of the simplified icon and generating all sizes

Additional context
I believe this feature may be supported by the favicons library, but am unsure if that's true.

I like the idea but it would be probably a lot of work to build it..

Do you want to do a POC as a pull request?

Hey, sorry. I don't have time to work on it. I'd love the feature but will move forward with the third alternative for now.

This plugin relies on favicons package and that package actually allows to pass multiple sources. It picks a source image by its size. (there are some frictions in the current version 6.2.2 and it is recommended to sort source images by size in advance, upcoming 7.0.0 does not have such issue).
