314: Remove CLI config file in favour of parameters r=thomaseizinger a=da-kami

Fixes #282 

The CLI has sensible default values for all parameters,
thus a config file is not really an advantage but just
keeps getting in our way, so re remove it.

Trait impls on `Data` needed for structopt, see https://docs.rs/structopt/0.3.21/structopt/#default-values
