Please add compatibility for the Slimefun Repo

Problem:
Please add compatibility for the Slimefun custom repo, made by "TheBusyBiscuit"
https://thebusybiscuit.github.io/builds/

Solution:
So this would work very similar to how the current Github source works.
For repo name, input of "TheBusyBuscuit" would be the contributor, then "Slimefun4 (master)" would be the project or asset name.
repo-name: TheBusyBiscuit/Slimefun4/master/
Then for asset name, input "Slimefun4 - DEV"
asset-name: Slimefun4 - DEV

And the same format could be used for all plugins in this repo, there's 72 active plugins in this repo.
Please add support for this!
Thank you.
