feat(nix/readTree): give better error message when not a function r/2224
When a file is added to the depot tree that is picked up by read-tree, but it’s not a function like ({...}: {}), `readTree` will fail on the function application, leading to a bad error message. We can do slightly better, by checking the type and throwing a nicer trace message. `assertMsg` is copied from `nixpkgs/lib/assert.nix`, since at this point we don’t have a reference to the lib. There is another evaluation failure that can happen, which is when the function we try to call does not have dots; however, nix does not provide any inflection capabilies for checking whether a function attrset is open (`builtins.functionArgs` only tells us the attrs it mentions explicitly). Maybe the locality of the error could be improved somehow.
