feature release

- you can open / crate .tar.zst files now
- direct compressing of files with zstd works also
- you can also open files compressed with pzstd
- next version will do also threaded compression like pzstd does
- zst files can be registred with 7-Zip ZS now
- update to latest zstd dev release v1.0.1
- the About Box will give you a hint, that this 7-Zip is not the default one
