feature request: zellij add support for layouts

[colemickens]

Description

I want to adopt zjstatus: https://github.com/dj95/zjstatus

It looks like that entails including the plugin in a new custom layout file in layouts/ . Then launching with that layout or setting default_layout in the config.

I can import the KDL converter and use xdgConfigFile to do this by hand, but it would be nice to have module options for it.

example usage: https://github.com/colemickens/nixcfg/commit/90914d2dd8cbecda7f785f2bb833d55c3887347b

but I can't really figure out if there's even a way to express that KDL in Nix...

What do others propose the configuration api look like for this? Maybe just accept a string? This approach would certainly be more straight-forward in my opinion than writing the layouts directly as nix code then serializing the data to kdl nodes from nix. Given kdl node names carry attributes while nix syntax structured data more akin to json it would be more difficult to implement and likely less intuitive to users. Thoughts on implementing it this way?
