- Rename "filename" types which no longer map directly to a filename (LayerFileName -> LayerName) - Add a -v1- part to local layer paths to smooth the path to future updates (we anticipate a -v2- that uses checksums later) - Rename methods that refer to the string-ized version of a LayerName to no longer be called "filename" - Refactor reconcile() function to use a LocalLayerFileMetadata type that includes the local path, rather than carrying local path separately in a tuple and unwrap()'ing it later.
