rust: pvattest-Rust

Add a CLI compatible Rust implementation of pvattest-C.
 - All (non-experimental) options are supported and work exactly as in
   the C implementation. For some options/parameters new variants are
   available.
 - `perform` now also accepts positional arguments, while keep accepting
   -i and -o  that was mandatory in the C implementation.
 - `version` may also be a command instead of an option now.
 - -V is deprecated
 - -v increases verbosity instead of showing the version
 - all experimental options are dropped
