Support recursive copy of files

[SaraVieira]

Right now axoasset only supports copying one asset at a time, it would be nice if it supported a recursive option where we could just pass a origin_folder and a dist_folder and it would copy the files and create the folders

example code used in fs_extra: https://docs.rs/fs_extra/latest/src/fs_extra/lib.rs.html#190-223
