/** @brief Resolve an argument that is generally a file, but could be something that
* is easy to resolve to a file, like a <lookup path> or a tarball URL.
*
* In particular, this will resolve and fetch pseudo-URLs starting with
* @c channel:, flakerefs starting with @c flake:, and anything that
* @ref nix::fetchers::downloadTarball() can take.
*
* Non-absolute files are looked up relative to the current directory(?)
* FIXME: the process's current directory or EvalState's current directory?
*
* @param state The nix::EvalState to base settings, store, and nixPath from.
*
* @param fileArg The the path-ish to resolve.
*
* @return A nix::SourcePath to the resolved and fetched file.
*
* @exception nix::FileTransferError from nix::fetchers::downloadTarball(). Probably others.
*
* @exception nix::ThrownError for failed search path lookup. Probably others.
