Most pvattest subcommands use the command line option -i <input> and -o
<output> to specify file input and output respectively. pvattest check
however only uses positional arguments for <input> and <output>, e.g.
$ pvattest check input.bin output.yaml
This provides an inconsistent user interface within the tool and may
confuse users.
Add the command -i and -o option to the check subcommand to bring it in
line with the rest of the tool.
$ pvattest check -i input.bin -o output.yaml

Show -i & -o option and display them in the help output. Showing the
additional options to the user may provide a better experience. Users
may expect -i /-o options as other subcommands have them as well.

If pvattest perform is executed with options on a non-s390 system the
user gets misleading error messages as the options are not defined.
> pvattest perform -i attestation_request.bin -o attresp.bin
error: unexpected argument '-i' found
This may lead the user to think wrong arguments where chosen, which is
not entirely true as they are valid on s390. The more helpful error
message would be
error: Command only available on s390x
Which is already the case if no arguments are given.
Solve this by allowing non-s390 systems to parse the options:
> pvattest perform -i attestation_request.bin -o attresp.bin
error: Command only available on s390x
While at it ignore some unused code warnings in the exchange format code
that appear on non-s390 systems as not all code is used.

Check if the SE-guests machine firmware is in an IBM approved state.
The machine firmware version can be obtained via setting a flag in the
attestation request.
The opaque 320 byte value from firmware is forwarded to an IBM server
that verifies the firmware value and confirms if the machine is in an
IBM approved firmware state.

Add a check to verify the hash over the Secret Store in the guest UV
storage. During 'create' the user can request that hash via a flag. During
'check' the user specifies the Add Secret requests and check whether the store is
locked. If the calculated hash over this state matches the one reported
by attestation, this check is successful.

Add a new command: check. This allows users to perform policy checks on
the Attestation result.
The host-key hashes, and the user-data can be tested for certain values.
While at it fix some typos and enable CSV parsing for the Additional-data flags.
Example:
```
pvattest check attestresp checkresult -k hkd0.crt,hkd1.crt
--host-key-check AttKeyCheck
```

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
