Add support for reading/writing zipped mappings (#199)

* Add support to read/write Enigma mappings from ZIP

Takes any path which points to a ZIP as wanting to be read/written as a ZIP
Paths from an existing ZIP file system will be correctly handled as directories

* Fix deleting a path needing to be from the default file system

* Allow calling MapSpecializedMethodsCommand directly

* Fix indentation

* Missing static
