morefs: A Collection of fsspec-based Filesystems

morefs is a Python library offering a collection of self-contained filesystems built on top of `fsspec`. It currently provides `AsyncLocalFileSystem`, `DictFileSystem`, and `OverlayFileSystem` to extend `fsspec`'s capabilities for asynchronous local operations, in-memory dictionary-backed storage, and layered filesystem views, respectively. The library is actively maintained, with the current version being 0.2.2, and releases occur as needed to address compatibility or introduce new features.
