Add ELEGOO filament as a native filament#211

It’s pretty much in the title but this is just requesting you to add ELEGOO as a brand to the filament tab.

This can be done via our open source filament database, the Open Filament Database; https://github.com/SimplyPrint/open-filament-database/

More info on exactly how to contribute to it, so that you can help us add this brand, will follow soon. Check the GitHub page for more info :)
