Restructure `pathway-system` (#33) This does a lot of restructuring: - adds `pathway-compat-*` libs for multi-layer wrappers over `base`, `directory`, and `filepath`; - adds `variant`-based open sum types for recovering `IO` errors; and - has `pathway-system` depend on the new `pathway-compat-*` packages.
