instead preserve save original to backup file

Hi,

i am very happy with MinifyAll in VS Code, thank you very much 💯

I just want to request the feature to save the minified content and the original content to the backup file, like so:

'myStyles.css' (minified)
'myStyles-orgin.css'

'index.html' (minified)
'index-orgin.html'

and so on ... ;-)

Please make this available as switchable option because i want to do this via context menu instead of Minify this document and preserve the original

This way I avoid my server having to deliver -min.css instead of .css and so on...

[welcome]
