- update to 5.0:
* It is now possible to specify a codec for archive entry
metadata (`pathname`, `linkpath`, `uname` and `gname`)
* **BREAKING:** If you use the `archive_read_class` and
`archive_write_class` arguments, the classes you provide will
receive a codec name as a second positional argument.
* The `timestamp_nsec` arguments of the legacy
`ArchiveEntry.set_{a,c,m}time` methods are now optional
* Removed obsolete dependencies (`mock` and `six`) from
