“Read from uncompressed kzip” feature

[my-tien]

It is possible to write .k.zip cubes into a folder with save_to_kzip_path_only and then to compress the folder in the end with compress_kzip.
But there isn’t a function to read cubes from the uncompressed folder which might be useful if the cube should be updated.
