Ability to add a mod by download link

[GeraldTM]

I quite like the modrinth app and plan to use it to create modpacks. However,the (understandable) inability to download mods from other platforms like curseforge is unfortunate as some mods still stay as curse only. My workaround concept for this is as follows: have a button to "add a mod by download link" where you can paste the curseforge or other url, and add the mod to the modpack
