Overlays of slices config

[shyim]

I would like to have overlays of the slices config. Right now I have a fork of chisel releases and have my additional packages. This is annoying. I would love to have the option to have overlays like:

chisel cut --release github:canonical/chisel-releases#ubuntu-24.04,github:shyim/xxxx:#branch,file:.

and in my Repository or local path, I would only define the newly added slices; the order of overlays specifies the inheritance

Thanks for the suggestion @shyim

This is definitely something we could consider for the future. It is very unlikely it would land before mid 2024, but still, I'll keep it open until we take it under consideration ;)
