Invalid argument error

[j-ti]

The current version compiles, the module can be imported, however when using the module, a invalid argument error appears. Which is most probably due to the wrong use of commands in this simple test case.

Plan: I now want to switch from the simple balance example test case to the actual BEST-Energy calls of the updated dependency.
Addresses: olisystems/BEST-Energy#40

Version 1 (current): Using parse from vec
Version 2: Use commands.rs definition to create a Command and insert it as paramter in Cli constructor

Output of Version 1

Verson2:
Currently it is not possible to directly use the trusted commands in src/lib.rs as trusted_base_cli is a private module, i.e.

# not possible
use integritee_cli::trusted_base_cli::commands;

Adopt version 2: Established by merge #2 including changes in dependency to make things public
