225: lib: only readDir if path exists with safeReadDir r=nrdxp a=Pacman99
After doing this for the second time, I realized it might be good to make a lib function for it and do it across lib.
Create a function called `safeReadDir` that only uses `builtins.readDir` if the path exists. With `optionalAttrs` any function that relies on the output won't fail since they still get an empty attrset.
Then replace all uses of `readDir` with the safe version.

224: Allow for directories in module-list r=nrdxp a=Pacman99
fixes#221
building on #222 this PR improves the lib functions pathsToImportedAttrs and pathsIn. First to add support for directories. This does not support actually passing a file in a directory, so `./matrix/default.nix` won't work but `./matrix` will - I should probably document this somewhere.
Also I moved the filtering for nix files to `pathsIn`, since its only necessary for auto-import. We can assume that users would pass proper files in `module-list.nix`.

216: Move host and suite implementation logic to lib r=nrdxp a=Pacman99
This is just the `mkSuites` and `mkHosts` part of the `mkDevos` PR. I would like to avoid changing mkSuites and mkHosts api, to make it easier to rebase changes into the mkDevos branch. But if necessary we can change them. And to that end, there is some more logic added to the flake.nix now which would ideally not be there if devos was meant to be a template. But since the goal is to move towards a lib function with template, this is just a step in that direction.
